IPv6 Transition

The IPv4 Market: 2017 and Beyond

The IPv4 market has grown significantly in the last four years. It finished particularly strong in 2017, both in terms of the total volume of addresses traded and overall number of intra- and inter-RIR transactions in the ARIN region. Over the last four years, the steady and sometimes substantial growth in the number of transactions has been mostly attributable to a dramatic increase in small block trades of fewer than 4,000 addresses. more

The Christmas Goat and IPv6 (Year 4)

This year, 2013, I got 24 days of IPv6 and DNSSEC measurements. All in all it created 15GB logs with more than 62 million rows. On the 21st of December, early in the morning, the goat was "traditionally" burnt down, however this year with one exception. Via the Swedish newspaper Expressen the arsonists anonymously took the blame and also filmed their own act. more

A Look Back at the World of IP Addressing in 2020: What Changed and What It Means

Time for another annual roundup from the world of IP addresses. Let's see what has changed in the past 12 months in addressing the Internet and look at how IP address allocation information can inform us of the changing nature of the network itself. Back around 1992, the IETF gazed into their crystal ball and tried to understand how the Internet was going to evolve and what demands would be placed on the addressing system as part of the "IP Next Generation" study.  more

A Three Minute Guide to Network Automation Bliss

The cloud computing paradigm has been making steady progress in 2016. With the DevOps model making its way from cloud to networking, the business upside of fully automated service architectures is finally beginning to materialize. The associated service agility is expected to unleash new business models that transform the ways in which applications and connectivity can be consumed. more

Declaring IPv6 an Internet Standard

I've already shared my thoughts following a session of the IPv4 Sunset Working Group at IETF 95 that considered whether to declare IPv4 an "Historic" specification. Of course, as one would expect for a meeting of a Standards Development Organization (SDO), that wasn't the only standards process discussion through the week. Another session, this time in the IPv6 Maintenance Working Group, considered the related topic of whether to make the IPv6 specification a full Internet Standard. Let's look at that proposal. more

IPv6 for the Masses

As the first semester of 2010 comes to a close, the IPv4 address pool has dropped to 6%. Another year and we will probably celebrate (mourn?) the end of the IANA IPv4 pool. As Vint Cerf commented on the topic of depletion in an e-mail to Bob Hinden: 'Sic transit Gloria Mundi'. The view of an abyss or the fear of judgment day always focuses attention and as a result IPv6 adoption is finally picking up speed. The Google invitational IPv6 Conference in Mountain View clearly illustrated the point. more

Networks Announcing IPv6 Over Time: A Short Update

We regularly check the status of IPv6 deployment in the RIPE NCC service region, and in other service regions as well. One way to measure IPv6 deployment is to look at the percentage of networks announcing IPv6 prefixes and follow the developments over time. The RIPE NCC's IPv6-ASN graph shows the percentage of networks that announce one or more IPv6 prefixes in the global routing system. Having an IPv6 prefix visible in the global routing system is a required step for a network to actually start exchanging IPv6 traffic with other networks. more

If You Build It, They Will Come.

Only two years after signing the DNS root zone, the powerful lure of a secure global infrastructure for data distribution is starting to reveal itself. It is illustrated clearly by two proposed technical standardizations that seek to leverage secure DNS. To some degree these developments highlight the strength of DNS institutions and how they might fill gaps elsewhere in the Internet's governance. But an increasing reliance upon and concentration of power in the DNS also makes getting its global governance correct even more important. more

Is It Time to Create a Market for IPv4 Addresses?

It's fascinating to watch the Internet technical community grapple with policy economics as they face the problems creating by the growing scarcity of IPv4 addresses. The Internet Governance Project (IGP) is analyzing the innovative policies that ARIN, RIPE and APNIC are considering as a response to the depletion of IPv4 addresses. more

IPv6 and Airline Tickets… Tales of Two Transitions

The internet bus continues to accelerate straight into the IPv4 address depletion wall with spirited discussions continuing on how to divvy up the remnants of the address space. Obviously all five Regional Internet Registries (RIR's) want to make sure they get their fair share from IANA but what is a fair share remains the subject of interpretation. In the mean time, scenarios of a speculative land rush and auctions of ever smaller address blocks abound with unattractive consequences such as an explosion of the size of the routing table and a stunted growth of the global internet economy... In the meantime, the airline industry completed a rather significant migration of their own... more

From IPv6 Day to IPv6 Everyday

Quite a number of articles and blogs including one I contributed had IPv6 haruspices dissect the entrails and divine the future of the internet in the wake of the june 8th IPv6 World Day. It came and went with some trepidation, the internet did not go comatose and some marveled at and reported on traffic peaks they witnessed. Preparation of a keynote for the Gogonet Live conference in San Jose, provided me the opportunity to have a look at how some variables evolved since June... more

IPv6: Bring on Your Content!

Late last year a colleague quipped: you spent one third of your time on IPv6 this year, yet it still only generates 1% or so of the traffic. What are the chances of him uttering the same sentence coming December with IPv6 traffic still hovering barely over the one percent mark? more

NIST Releases a Profile for IPv6 in the U.S. Government for Comment - Comments Due Feb. 29

The National Institute for Standards and Technology (NIST) has released a second draft of a proposed standards profile to support the implementation of IPv6 by government agencies. "NIST developed the 'profile' to help ensure that IPv6-enabled federal information systems are interoperable, secure and able to co-exist with the current IPv4 systems." ...The White House's Office of Management and Budget declared in 2005 that all federal agencies shall migrated to IPv6 by June 30, 2008... more

IPv6: The Four Horsemen of the IPcalypse

War, famine, pestilence and death. They fought for the last IPv4 addresses, hoarded and sold them at outrageous prices, traffic and commerce came slowly to a halt... Pestilence invaded the internet... Bandits roam the lands. A retired general told recently that the internet looks like the North German plains, easy to invade. Cyberwar and Cybersecurity are becoming mainstream subjects and have increasing Government attention. more

Growth in IPv6-Capable DNS Infrastructure

In our last post on CircleID we showed encouraging growth in the number of IPv6-enabled networks. But announcing an IPv6 prefix is only one of the first steps a network operator should take when deploying IPv6. For a full IPv6 deployment, IPv6 needs to be enabled on network infrastructure and made available to end users. One key piece of infrastructure for which we can measure IPv6 capabilities are DNS resolvers. more
