The Hidden Value of IPv4 Addresses and How to Take Advantage of Rising IPv4 Address Value

Everything You Need to Know About IPv4 vs. IPv6

IPv4 Markets / Recently Commented

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

VPN Security Flaw Makes IP Address of Users Using IPv6 Easily Traceable

Duncan Geere reporting in Wired: "Since the slow introduction of internet monitoring systems around the world began, more and more people have attempted to preserve their privacy by signing up for VPN services like the Pirate Bay's Ipredator and Pirate Party offering Relakks. But it turns out that there's a gaping security flaw in these services that allows individual users to be identified..." 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

Take IP Address Management Seriously; Your Business Depends on It

Let's start by stating the obvious: All business communications depend on IP addresses. Without an IP address, you simply can't communicate over the network. No IP address means no access to your email server, no access to your website, and no cell phone or VoIP access. So much for the new VoIP system installed last month. What does that mean to you? more

IPv6: Circling the IPv4 Wagons for a Last Stand

The last remaining stocks disappear from the shelves more quickly than ever before . . . IPv4 addresses that is. As the ARIN met in Toronto in April, an inordinate amount of time was spent yet again debating proposals on how to handle the dwindling stock of IPv4 addresses. I get the distinct impression that some people will still be tabling proposals and discuss the issue long after the last IPv4 block has been allocated by IANA and even the RIR's themselves. more

OECD Reports on State of IPv6 Deployment for Policy Makers

OECD, Organization for Economic Co-Operation and Development, has released a report for policy makers assessing the level of IPv6 deployment around the world. "[T]he timely deployment of IPv6 by network operators and content/application providers is an increasing priority for all Internet stakeholders. In terms of public policy, IPv6 plays an important role in enabling growth of the Internet to support further innovation. In addition, security, interoperability and competition issues are involved with the depletion of IPv4." more

Regional Internet Registries Conducting Internet Community Consultation on ITU IPv6 CIR Proposal

The Regional Internet Registries are conducting a Internet community consultation process regarding the recent ITU IPv6 Country Internet Registry (CIR) proposal. In collaboration with the other Regional Internet Registries, APNIC hosted a special session at APNIC 29 / APRICOT 2010 to give the global Internet Community an opportunity to discuss the issues and ramifications of the alternative model proposed by the ITU. For those interested in the outcome of the recent face-to-face session, a raw transcript and session summary statement are available... more

Announcement: Critical Internet Infrastructure WG is Now Open to Public Participation

ISOTF Critical Internet Infrastructure WG is now open to public participation. The group holds top experts on internet technology, critical infrastructure, and internet governance, from around the globe. Together, we discuss definitions, problems, challenges and solutions in securing and assuring the reliability of the global internet infrastructure, which is critical infrastructure for a growing number of nations, corporations and indeed, individuals -- world wide. more

RIPE at 59!

RIPE, or Réseaux IP Européens, is a collaborative forum open to all parties interested in wide area IP networks in Europe and beyond... RIPE has been a feature of the European Internet landscape for some twenty years now, and it continues to be a progressive and engaged forum. These days RIPE meets twice a year, and the most recent meeting was held at Lisbon, Portugal, from the 5th to the 9th of October 2009. In this column I'd like to share some of my impressions of this meeting. more

Root Scaling Study Report is Out

Earlier this year, ICANN began to seriously consider the various effects of adding DNS protocol features and new entries into the Root Zone. With the NTIA announcement that the Root Zone would be signed this year, a root scaling study team was formed to assess the scalability of the processes used to create and publish the Root Zone. Properly considered, this study should have lasted longer than the 120 days -- but the results suggest that scaling up the root zone is not without risk -- and these risks should be considered before "green-lighting" any significant changes to the root zone or its processes. I, for one, would be interested in any comments, observations, etc. (The caveats: This was, by most measures, a rush job. My spin: This is or should be a risk assessment tool.) Full report available here [PDF]. more

ARIN’s New CEO: IPv6 One of the Most Critical Internet Issues Today

The American Registry for Internet Numbers (ARIN) named John Curran as president and chief executive officer, effective July 1, 2009. Since January 1, 2009, Curran has served as acting president and CEO of ARIN. He is a founding member of the ARIN Board of Trustees and served as chairman from August 1997 to December 2008. Curran has also been a valuable participant on CircleID where he has shared his views on a number key issues such as IPv6. more

Internet Records Retention Bill

A lot of pixels have been spilled lately over an Internet records retention bill recently introduced in both the House and the Senate. The goal is to fight child pornography. That's a worthwhile goal; however, I think these bills will do little to further it. Worse yet, I think that at least two of the provisions of the bill are likely to have bad side effects... more

The Slow Mainstreaming of IPv6

Slowly, we’re making progress mainstreaming IPv6. I wanted to post on a few interesting developments. Late last month, Netflix got an IPv6 allocation from ARIN, and they’re advertising it in BGP... I look forward to the day I can stream movies to my Netflix set-top box over IPv6. more

IPv6 Floating on the Ethernet

Remarkable how Ethernet has evolved and been widely adopted over this quarter of a century period extending its reach from LAN to MAN to WAN and from 10meg to 10gigE. One has to credit the IEEE for quite an efficient job as a standards body. Over in the IP world, this month of March will see IETF 74 meet in San Francisco and continue to ponder transitions, address translations, double translations, even carrier grade translations... more
