Internet Evolution Approaches at ITU T why should we care? NANOG 2022-10-26 | The International Telecommunication Union’s Telecommunication Standardization Sector (ITU-T) received a proposal two years ago to begin work on designing a “new information and communications network with new protocol system” to meet the needs of a future network – the “New IP, Shaping Future Network” proposal. The proposal’s proponents made various claims about the issues that the current network faces as a basis for developing a new design. Many of the raised points have been widely researched in the technical and standards communities for decades and for which solutions already exist. Others deal with areas that are already the subject of current standardization or study. In addition, some of these ideas were reflected in earlier work of the ITU-T Study Group (SG13) Focus Group on Future Networks 2030.In December 2020, New IP was not approved as new work items for the next study period of ITU-T. Since December, however, elements of the New IP proposal were presented at the March and September 2021 meetings of ITU-T SG13 which is why it is relevant to continue to discuss the proposal. Also, some proposals for resolutions submitted to the World Telecommunication Standardization Assembly which took place in March 1-9, 2022, included elements of the NewIP proposal.Hosein Badran: Dr. Hosein Badran holds the position of Regional Technical Advisor – North America Bureau with the Internet Society, based in Ottawa, Canada.

Tutorial: How Optical Networking Transformed Our World NANOG 2022-10-26 | In 1970 two technology pathways finally came together. The semiconductor laser and low attenuation optical fiber; technologies based on very different materials and unrelated branches of physics. Over 70 years of historical innovation in each of these areas finally converged at a point where the commercial application for high speed communications over long distances was now possible for emerging computer platforms.In this tutorial, Geoff Bennett will explain the timeline of innovation for optical fiber - the quest to create a communication pathway that is thinner than a human hair, yet has a potential capacity that a 1970s engineer would often summarize as "practically infinite".He will then turn his attention to the development of a totally new light source to fill the new medium - the semiconductor laser. The story is littered with a Who's Who of science and technology, not to mention an armful of Nobel Prizes.But the real story begins when these two technologies come together, and are joined by amplification breakthroughs like the EDFA, and the revolution of coherent transmission and processing.
Efficient network automation with Nornir and Napalm NANOG 2022-10-26 | Nornir is a vendor-neutral, open-source project. It is a multi-threaded network automation framework that abstracts inventory and task execution like configuring the devices, validating the operational data, and enabling the services on the provided hosts which are part of the inventory. As it is multithreaded, it allows managing the configuration of multiple network devices concurrently. NAPALM is a vendor-neutral, cross-platform open source project. It is a python library that provides a set of methodologies for configuration management and operational data retrieval. It supports Cisco IOS-XR, Cisco IOS, Cisco NX-OS, Juniper JunOS, and Arista EOS network operating systems. This session gives an overview of Nornir, Napalm, and the process of concurrently executing tasks to manage network configuration and operational data.Neelima Parakala: Neelima Parakala is a Technical Marketing Engineer at Cisco, focusing on Service Provider products and network automation tools.

Lightning Talk: Serving Security Updates to Every Linux Server in the World NANOG 2022-10-26 | Unlike commercial operating systems, free Linux distributions don't have a Content Distribution Network budget to serve updates to all their users, so they rely on volunteer run mirrors hosted by the community to make their operating systems and updates available online. Unfortunately, the traditional hosts of these sites are on the decline, so a new generation of Linux mirror hosts need to step up and continue to ensure that updates are available when needed.Speaker: Kenneth Finnegan
Being a better Netizen: MANRS @ DigitalOcean NANOG 2022-10-26 | One of the core values at DigitalOcean is "Our community is bigger than us" - because we're a member of the Internet community, we felt it was necessary to do better and improve our routing security posture. So during 2020, we set out to become compliant with the MANRS Cloud and CDN program. This presentation will guide you through how we interpreted the MANRS guidelines and some of the tooling we used to implement better routing security in our global network.
Responsiveness under working conditions NANOG 2022-10-26 | Since the early days of the Internet, capacity has been the prime metric to quantify the quality of the Internet access. While capacity was the primary challenge back in those days, we have successfully reached a point where the vast majority of users can easily access sufficient capacity for the majority of the use-cases. But still, Internet experience is often lacking the smoothness that we would expect. Video-conferencing still has frequent issues, video gaming is rarely a smooth experience and web-browsing still suffers from bad page-load times.We present a new metric, called "Responsiveness under working conditions", which significantly broadens the scope far beyond traditional capacity and latency measurements. This metric aims at quantifying the network's ability to provide low latency while at the same time providing high capacity. The measurement methodology not only measures the network, but also the end-host networking stack. We will describe how measuring responsiveness will allow to detect deep buffers in the server's networking stack and how it affects the end-user experience. Further, we describe steps that can be taken to reduce those buffers. We will conclude this talk by providing resources and open-source tools to allow everyone to reproduce the same measurement on their infrastructure and tune their networking stack for the benefit of their end-users.Christoph Paasch: Christoph Paasch has been working on transport layer networking since 2010. Focusing on extensions to TCP, like Multipath TCP or TCP Fast Open. From specification (in the case of MPTCP) and research to the implementation and large scale deployments at Apple. Lately he has shifted his focus on improving the network properties that really matter to the end-user experience by exposing measurement tools to raise awareness to these issues. "Responsiveness under working conditions" being now the first primary target.
Increasing IPv6 Utilization in Consumer Networks NANOG 2022-10-26 | With so much content available via IPv6, why isn't more traffic using it?We'll talk about why this is and what we can do about it.
Seamless Data Center Interconnect options using EVPN & various tunnel stitching NANOG 2022-10-26 | The data center interconnect became even more important for fast and secure data replication during the global pandemic era. With seamless DCI using various tunnel stitching options we can simplify and fully control where the data gets replicated between the data centers' geographically dispersed locations. The session will be focused on the rfc9014 interconnect design and implementation using the BGP EVPN control plane and various encapsulation stitching options.Michal Styszynski: Michal is currently part of the Product Management team at Juniper Networks cloud-ready data center business unit. He joined Juniper Networks over 10 years ago and before his current PLM role, he had also worked in technical marketing and product consulting, focusing on data center and storage networking projects for major Telcos and large enterprises.

NOGs within the RIPE Community NANOG 2022-10-26 | The NOG landscape in the RIPE community is varied, some are highly active communities which meet regularly, some are simply telegram groups. What is important to some, may not be to others. This means trying to understand each NOG can be a difficult task.Working in collaboration with NOG organisers throughout the RIPE NCC service region and beyond, the RIPE NCC created a survey which has been sent to all NOG participants. The purpose of this survey is to get a better understanding of what NOG participants want, what prevents them from participating (both at events and on communication channels), what content they would like to see, what NOGs can do to continue to attract new people and more.This information is important to RIPE NCC as the NOG communities often comprise of the core people involved in maintaining an open, inclusive, collaborative Internet model in each country or region. If we have a better understanding of these NOGs on a more granular level, we can better tailor our services, training, and outreach in these regions.My presentation will highlight the results of this survey. I will be able to give not just an overview of the NOGs in our region, but also highlight interesting points with regards to specific regions and countries. This presentation will also allow me to give a clear update on what is currently the most important topics throughout our service region.Alastair Strachan: Alastair Strachan is the Community Development Officer at the RIPE NCC. In this role, he works to strengthen the RIPE NCC's engagement with the RIPE NCC membership, the RIPE community, government, law enforcement and other Internet stakeholders. Alastair coordinates the RIPE NCC Community Projects Fund which gives funding to non-commercial projects that benefit the RIPE community.
Native American Nations: The pandemic was a catalyst for the need for connectivity, but are we conne NANOG 2022-10-26 | As we all know, the pandemic was the biggest marketing campaign for getting connected to broadband. Trapped in your home with quarantine restrictions and the need to communicate and participate in jobs, education, and life in general.Now think about being sent home from your job to "telecommute" and there is no broadband, you don't even have a provider to call to get connected. You have now been furloughed, due to the lack of Internet. Your children have been sent home from school with a laptop computer and told to participate in their schooling online and attend classes with video conferencing. Effectively, your kids have just missed a year+ of school...The Federal Government made some steps to actively address these issues with funding... Has it helped?Some States have made significant efforts to build new infrastructure, and some have included their Tribes as a priority.California has focused nearly $4Billion on advancing the middle-mile Infrastructure of the State (GoldenStateNet.org), the Tribes are, for the most part, included.Many other efforts have taken place to address the lack of connectivity in Indian Country, many of them are driven from within the Tribes.The Tribal Broadband Bootcamps (tribalbroadbandbootcamp.com) were spawned, due to the demand for training during the pandemic, addressing specific network building training needs and sponsoring participants to attend.The Tribal Resource Center (tribalresourcecenter.net) was conceived and is growing into a resource aggregator for developing Tribal Broadband.Arcadian Infracom is funded with a partnership with TIAA, and is moving towards completing solutions that will support many Tribes with the routes in development.
Internet Impacts Due to the War in Ukraine NANOG 2022-10-26 | Russia's invasion of Ukraine occurred just after NANOG 84. In addition to the tragic loss of life and destruction the subsequent fighting has wrought, the conflict has had measurable impacts on the Internet.DDoS attacks targeting Ukraine were followed by retaliatory attacks against Russian networks. Outages in Ukraine have resulted from the fighting as well as from "cyberattacks". Ukraine asked ICANN and RIPE to disconnect Russia while Russia moved to block Internet access to independent media which led to a BGP hijack of Twitter.Despite all of this, the Ukrainian Internet has proved to be resilient due in large part to the courageous efforts of the country's telecom technicians. This talk summarizes the Internet impacts from the recent war in Ukraine.Doug Madory: Doug Madory is the Director of Internet Analysis for Kentik where he works on Internet infrastructure analysis. The Washington Post dubbed him “The Man who can see the Internet" for his reputation in identifying significant developments in the structure of the Internet. Doug is regularly quoted by major news outlets about developments ranging from national blackouts to BGP hijacks to the activation of submarine cables. Prior to Kentik, he was the lead analyst for Oracle's Internet Intelligence team (formerly Dyn Research and Renesys).

ML Driven Bandwidth Forecasting NANOG 2022-10-25 | Bandwidth management in a network is critical for efficient network utilization. Automatic bandwidth allocation using the classical maximum-average bandwidth method is limited in its capability in part due to its reactive nature and requiring many interdependent configurations to make it effective. We present a light weight, modular ML Driven Bandwidth Forecasting Framework that can proactively forecast bandwidth values based on historical patterns in the data. Our approach includes an ensemble of time series forecasting methods along with the traditional max-average approach. Additionally, we highlight several applications based on our framework that can enhance network performance.Venkata Naga Chaitanya Munukutla: Hi there, I’m a Staff Software Engineer at Juniper Networks. In my 9+ years working in Networking industry, I enjoyed using my skills to solve critical challenges faced by network operators. My primary focus has been applications of Data analytics and Machine learning to solve tomorrow's problems today.Speaker:Venkata Naga Chaitanya Munukutla - Juniper Networks
Keynote: Me, NTP, The NTP Project, and Network Time Foundation NANOG 2022-10-25 | Keynote: Me, NTP, The NTP Project, and Network Time Foundation - How We Got Here: Welcome to my HallucinationTimekeeping has been a “thing” for humans for thousands of years. We generally do it without thinking about it. Doing it provably well, or even “better”, takes a possibly surprising amount of attention, consideration, and collaboration. Maybe even perspicacity.The first significant attempt to synchronize accurate network time might have been documented by Prof. David L. Mills, PhD, in February of 1981, in IEN-173. Dave’s work on the Network Time Protocol, with the help of a few other dedicated folks, quickly gelled and evolved. The evolution and refinement of NTP continues.This talk will cover various milestones that have occurred in my life, in the NTP Project, and with Network Time Foundation. With any luck, some aspects of the symbiotic connections around NTP and some of its primary contributors will be highlighted.Harlan Stenn: Harlan Stenn is a nearly 50-year veteran of the IT industry. Harlan began programming computers in high school in 1971. He holds a bachelors degree in Business Administration (Accounting) from The Colorado College in Colorado Springs, and an MSE in Computer Science from Washington University in St. Louis. A well-versed entrepreneur, Harlan has launched several successful businesses and has been a respected, sought-after I/T consultant and contractor for decades who is well known for writing astonishingly portable C code since the early 1980s. He became interested in the issues around timekeeping on computers in the early 80s, and started submitting bug fixes and portability improvements to the Network Time Protocol codebase, then contributing to the NTP Project in the 90s. Shortly thereafter he became the project manager/release engineer/code monkey. To put it another way, if NTP is Dave Mills' edifice, Harlan is its janitor. In mid-2011 he started Network Time Foundation (NTF), with the mission to provide direct services and support to improve the state of accurate computer network timekeeping. NTF now works with several time-related projects, including NTP, Ntimed, Linux PTP, RADclock, and the General Timestamp API and Library. The GTSAPI is a way to make sure that a timestamp contains enough information to be useful outside of the system on which it was “taken". Several new projects are in the works, including Khronos, and several SyncE packages. Heiko Gerstung, a Managing Director at Meinberg Funkuhren GmbH & CO. (one of Network Time Foundation’s earliest partners) describes Harlan’s job thus: “Harlan is doing a fantastic job as the Programme Manager for the public NTP project. This "herding cats"-like task requires a vast amount of patience and knowledge and it seems that he has that and much more! Some of the cats are rather big and fancy and I am always puzzled to learn how the "PM" manages to maintain releases and organizational things single- handedly." Harlan has been active in the public domain software and open-source communities since 1976. When he is away from the keyboard, he enjoys cooking (especially baking and grilling) and photography.Speaker:Harlan Stenn - Network Time Protocol (NTP) Project Manager, President of Network Time Foundation
Internet Routing and Traffic Security – A view from Cloud and CDN Providers NANOG 2022-10-25 | Routing and traffic security is one of the top challenges faced by the Internet today. A reliable and secure Internet is essential for society, but the trust model on which connectivity is based has eroded through BGP hijacks, routing misconfigurations, and DDoS attacks. While the Internet community has pursued several practical mechanisms to protect the Internet from these vulnerabilities, it is clear that the pace of adoption and deployment needs to increase further. Cloud and CDN providers are subject to these same issues, and also have some unique challenges that have led to collaborations in forums such as MANRS to introduce additional best practices. This session includes perspectives from several cloud and content providers to share their progress and experience implementing routing and traffic security to protect the Internet, and highlight how they are working with the wider Internet community toward the same goal.Presentation 1: Internet SocietyTitle: Decentralized security of a globally distributed system: challenges and opportunities”Speaker: Andrei RobachevskySummary/Abstract: The talk will discuss a broader question of challenges and opportunities of solving security problems of a decentralized and globally distributed system, such as Internet routing. MANRS, launched in 2014 by 9 network operators, has grown to more than 800 participants, covering 4 programs focused on network operators, IXPs, CDN& Cloud providers and network equipment vendors. What is the most effective way participants from these groups can contribute to better routing security? What are the incentives, material and immaterial, for doing so? The presentation will discuss the efficacy of the approach and its sustainability, as well as the efforts to improve both. In particular, it will talk about developing another tier - MANRS+ aimed at providing higher security assurance, especially in business-to-business relationships and handing the effort, initially coordinated by the Internet Society, fully to the community.Presentation 2: GoogleTitle: A multi-pronged approach for securing Internet routingSpeaker: Anees ShaikhSummary/abstract:Protecting networks and users from Internet routing disruptions cannot be achieved with a single “silver bullet” solution – the threats are varied, and require development and deployment of multiple technical capabilities. Google has deployed a combination of mechanisms, including route filtering systems, public registrations to enable correctness checks by other networks, and monitoring systems that provide early detection when routes are hijacked. We have also emphasized collaboration with the wider Internet operator community to improve data hygiene to enable all networks to deploy practical security mechanisms.Presentation 3: AmazonTitle: How AWS is helping to secure internet routing Speaker: Fredrik KorsbäckSummary/Abstract: To help put an end to BGP hijacking, AWS has been working closely with other industry leaders to make an industry-wide standard practice the use of Resource Public Key Infrastructure (RPKI) to digitally sign route announcements. This is not a simple process, and it has taken lots of time, effort, and cooperation. We are happy to have over 99% of our IPv4 and IPv6 -Space covered under a Route Origination Authorization for two years, and that we are right now dropping RPKI invalid routes in every single Point-of-Presence for AS16509. In this talk we will look at how we did it and what we believe the future holds.Presentation 4: MicrosoftTitle: Building reliable RPKI infrastructure for large scale networks and Protect network against DDoS. Speaker: Somesh ChaturmohtaSummary / abstractMicrosoft operates one of the largest global networks in the world, connecting over 190 Microsoft Edge (PoP) locations and 61+ Azure regions. Protecting the Internet on this large scale network comes with unique challenges. In this talk, we talk about how at Microsoft we have deployed a reliable RPKI infrastructure and steps we are taking to protect the network against DDoS.
Going Dark: catastrophic security and privacy losses... NANOG 2022-10-25 | Going Dark: catastrophic security and privacy losses due to loss of visibility by managed private networksEffective modern site security is behavioral in nature. We cannot choose or exclude our endpoints nor validate their supply chains, and so to the extent that we manage digital risks posed by our endpoints we do it by watching the signals (packets and flows) they emit. Such observations are categorically untenable for investigative journalists and dissidents since the category is occupied by corrupt or authoritarian regimes or their national security apparatus -- as explained by E. Snowden in 2013 and as codified by the IETF in RFC 7258.Using the same protocols for mobile devices which accounted for most human-centric endpoint growth since 2010 as we do for fixed devices on networks controlled by families and businesses is disrupting our limited ability to secure the latter in order to defend against worst-case outcomes for the former. Several decades of unapologetic abuse by the powerful have led the IETF to reform the basic Internet protocol suite around TLS 1.3 with Encrypted Client Hello, DNS over HTTPS, and the replacement of TCP by the UDP-based QUIC protocol.In this new configuration, network operators will not be able to detect endpoint behavior changes corresponding to infection, takeover, poisoned software update, latent design dangers, predaceous grooming, insider corruption, or hundreds of other well-understood digital harms. Many such operators have not been warned about this "rules change" and deserve to have their expectations explicitly and immediately reset so that they can make new plans which will be practical in the next era.

Path Tracing NANOG 2022-06-17 | ECMP is a key in today’s IP network. It provides both efficiency and resilience. However, the detecting and troubleshooting of these ECMP paths remains a big challenge that faces many operators. FIB corruption or FIB misconfiguration at any node is one among many issues that can happen and may lead packets to follow a non ECMP Path. Path Tracing is a new solution that reveals all the unknows about ECMP. It allows operator to detect the currently available ECMP paths. They can also detect the ECMP Paths that were available at a given time in the past. Operators will be able also to know whether packets are following an ECMP Path or not. In addition, they can detect where packets are being drifted from the ECMP Path. Moreover, Path Tracing provides operators accurate end-to-end delay, per-hop delay, and the load of each interface that forwards the packet along the path.The Path Tracing dataplane is optimized for HW linerate implementation in the base HW forwarding pipeline. It requires minimum packet header parsing and processing. As a result, it can be implemented using a minimum number of micro code instructions. Path Tracing has also a rich ecosystem that includes several implementations in merchant silicon (Broadcom, Cisco, Marvell, others) and open source (Linux, VPP, P4, others). The solution is currently being standardized in the SPRING WG at IETF (datatracker.ietf.org/doc/draft-filsfils-spring-path-tracing/). In this presentation, we will review the path tracing solution and its ecosystem.Speaker: Michael Valentine
How to Debug RPKI Issues? Overview of RPKI Data Structures and Tooling NANOG 2022-06-17 | Everyone is doing RPKI nowadays, but ... how does one troubleshoot issues within RPKI itself?Getting RPKI Route Origin Validation going is straightforward: install a validator and point the EBGP routers to the RTR service endpoints. But what kind of files is the validator really pulling in? How? How to decode the binary formatted files into something human readable? What kind of references do the files contain towards each other? What the heck even is a "Signed Object"?In this presentation I'll share an overview of the data structures contained inside ROAs, GBRs, and BGPsec Router Keys, and explain how to use BSD/Linux utilities to inspect this type of data.Speaker: Job Snijders
Universal Acceptance of Valid Domain Names and Email Addresses: Challenges and Solutions NANOG 2022-06-17 | The Domain Name System (DNS) has evolved to include new, longer top-level domain (TLD) names, as well as TLDs and email addresses in various languages and scripts. The Universal Acceptance (UA) of these Internet identifiers means that they work seamlessly with all Internet-enabled applications, devices, and systems, some of which include email tools, webservers, content management systems, and more. Achieving UA-readiness is necessary for providing broader Internet access to global end users and driving digital inclusivity. Join the session to learn about the challenges and solutions for making UA a reality, including the gaps that need to be addressed by the technical community.Speaker: Sarmad Hussain
Optical Fiber Capacity Limits - Where Do We Go Next? NANOG 2022-06-17 | Optical fiber carries over 95% of terrestrial internet and private network traffic, and over 99% of international traffic via undersea cables. It is a miraculous medium, but it has fundamental limits in terms of the combination of capacity and reach. With almost 5 billion kilometres of optical fiber already installed, there is a strong incentive to extract as much capacity from existing fiber as possible.In this tutorial we explain what those fundamental limits are, and what we can do to get as close as we can to them based on a hierarchy of lowest impact to highest impact on the network:- The lowest impact implies using both the existing optical fibers in the ground today, and the existing line systems that are installed on those fibers.- Involving more investment would be to use existing fibers, but to enhance and upgrade the line systems.- And the highest investment option would be to deploy new fiber types.We will explain each of these options, including giving an explanation of emerging fiber technologies. We will also attempt to show the potential increase in capacity from each of these options.Speaker: Geoff Bennett
NANOG 85 Community Meeting NANOG 2022-06-17 | Don’t miss our Community Meeting for an opportunity to hear about what is happening with NANOG and the Program Committee.
20 Hours to 20 Minutes: a Story of Process, Automation, and Being Lazy! NANOG 2022-06-17 | Like many tasks, draining traffic off core routing device should be a simple task, but as you dive deeper into it (depending on the architecture) can become a complicated task with many moving parts to track and tasks to complete. This talk is going to walk through the process I went through to document, understand, automate, and improve the task of draining traffic off a routing device to be able to perform maintenances more often with low impact to customers. This talk is is both about the tool which was created but also about the process, and the iterative nature to get the tool to the state it's in now.Speaker: Charles Rumford
Panel: An Overview of EU and African NOGS NANOG 2022-06-17 | Following up on interest in learning how other NOGs work, we're bringing together five NOGs in a panel to give a quick overview of their Modus Operandi and general philosophy. Starting with a brief intro from NANOG, the format is short ~5 minute NOG presentations followed by a panel discussion around the benefits of the different models especially in the age of Covid. We would like to get audience interaction driving the Q&A section.The NOGs represneted on the panel are:NLNOG, NetherlandsSiNOG, SloveniaSAFNOG, Southern AfricaUKNOF, UKDENOG, GermanyENOG, Eurasian
Revisiting Power Provisioning for High-Bandwidth Routers NANOG 2022-06-17 | Power costs involve both consumption and provisioning. Traditional approaches to provisioning in large systems (e.g., Cisco ASR 9000, NCS 5500, Juniper MX/PTX, etc) tend to overestimate power requirements and push operators toward populating more power supplies than they really need. This is exacerbated by the wide range of optics power in the 400G generation (up to 800W / RU), which break traditional static approaches to power budgeting. Improving provisioning can save money (fewer PSUs and power feeds), free up facility resources (e.g., consume less cooling budget), and still prevent brownouts. It can also improve the efficiency of PSUs (they are most efficient at 30-100% load so too many PSUs can waste power).My experience is in leading enhancements to address this for Cisco's 8000 series, but the concepts apply to many platforms and operators will benefit if they are applied more broadly.In this talk, I'd like to encourage operators to revisit this area of sw/facility interaction as a way to explore efficiency improvements.Speaker; Lane Wigley
Keynote - IPv6, on by Default NANOG 2022-06-16 | Vint Cerf and John Brzozowski will share their thoughts on IPv6 as we celebrate the 10 year anniversary of World IPv6 Launch Day.Speakers: Vint Cerf and John Brzozowski
The Anatomy of the Most Challenging Network Engineering Interview Question NANOG 2022-06-16 | In October 2019, I presented “Some boring network engineering interview questions and how to replace them with smart ones” at NANOG 77 in Austin, TX (youtube.com/watch?v=g35UumfZ-H4&t=941s). An attempt to challenge the status quo around the quality of interview processes that was a new and different topic at the time. The recording of the session on YouTube has had one of the highest number of views and the authors received numerous questions and positive feedback. This time for NANOG 85, we are submitting a follow-up topic "The Anatomy of the Most Challenging Network Engineering Interview Question".Speaker: Kam Agahian
Panel: Buying and Selling IPv4 Addresses NANOG 2022-06-15 | There are a limited number of IPv4 addresses in existence—only 4.3 billion—and IPv4 exhaustion has become a major issue in the industry as the world is slow to adopt IPv6. For a new buyer or seller entering the market, it can become overwhelming to understand the basic process of transferring IPv4 space, protecting themselves from fraud, and ensuring their businesses receive resources on the right delivery time table. During this panel we’ll be hearing from a couple of experienced participants in the IPv4 market that can expand on mitigating transaction risks for buyers and sellers, evaluating pricing in an opaque market, using an IP address sale as an opportunity to upgrade your network, and navigating ARIN's transfer process.
Celebrating the 10th Anniversary of World IPv6 Launch NANOG 2022-06-15 | This presentation is both a celebration of the work performed to get IPv6 adoption to this point in North America. It also covers what work remains to continue to further IPv6 usage.Speaker: Scott Hogg
