We stand on the cusp of an explosion in the number of Internet-connected devices. The mobile revolution was just the beginning. Combined, the burgeoning wearables market and the Internet of Things will potentially create billions of new connected devices over the next few years. Every device will need an IP address and there are far too few available addresses within the IPv4 system to handle the sheer quantity of connections. It’s a problem that’s been predicted and solved for many years, in theory at least. But IPv6 is being adopted at a glacially slow pace. The reasons for the gradual adoption are simple to understand. It’s expensive. The Internet is made up of tens of millions of servers, routers, and switches that were designed to work with IPv4. Upgrading that infrastructure entails a significant capital investment.
CTU Telecommunications Specialist, Nigel Cassimire, shares what happened at this year’s Caribbean Internet Governance forum. The 10th edition of the Caribbean Internet Governance Forum (CIGF) was held at the Atlantis, Paradise Island Resort in The Bahamas from 6th to 8th August 2014. The CIGF is a regional, multi-stakeholder forum which was initiated by the Caribbean Telecommunications Union (CTU) and the Caribbean Community (CARICOM) Secretariat in 2005 in order to coordinate a regional approach to Internet Governance issues for the final session of the World Summit on the Information Society (WSIS) in Tunis that year. The CIGF has since been convened annually by the CTU and lays claim to being the first such regional forum in the world, all others having been convened after the initial global Internet Governance Forum in 2006.
Some thoughts on IPv6 reverse DNS. Lee Howard was speaking in the Sunset4 working group at IETF 90. He mentioned something that got me thinking. I have often discussed in my talks problems in IPv6 that were unanticipated. A lot of these problems are unintended consequences of very large subnet sizes. Some problems are outlined in RFC 6583. Lee mentioned another interesting problem, reverse DNS. Best practice [RFC1033] says that every Internet-reachable host should have a name (per RFC 1912) that is recorded with a PTR record in the .arpa zone. It also says that the PTR and the A record must match.
We recently attended the IGF-USA in Washington, DC and it got us thinking about why it is important for the ARIN community members to be involved with what is happening with the Internet as a whole. Here are three things that are important to us as users of the Internet and part of ARIN and the global Internet community. All Internet users should probably put these issues on their radar too. Evolution of the Internet governance ecosystem is occurring. With the National Telecommunications and Information Administration (NTIA) preparing to turn over oversight of the IANA stewardship functions to the multistakeholder community, there is a huge effort underway to determine a replacement that meets the requirements of the US government and more importantly the global Internet community’s needs for a healthy Internet.
I gave an Interop IPv6 presentation titled “Getting Serious About IPv6 – Go Big or Go Home” in Las Vegas on April 3, 2014. Since then, ARIN announced it has moved to Phase 4 (down to its last /8 of IPv4 – that happened on April 23, 2014). I think what surprised people the most (based on the feedback I got from the session) was that my argument about adoption for IPv6 had little to do with ARIN running out of IPv4. After all, this is what everyone talks about, that there are no more IPv4 addresses. My argument is: You have already deployed IPv6… you just didn’t know it. At this point, you may be scratching your head saying Ed is crazy, what is he talking about? Let me point out that all major OS platforms (and different flavors of those platforms) support IPv6 and have for a while now. It turns out that IPv6 is enabled (on by default) and preferred in almost all cases.
ARIN Advisory Council member, Cathy Aronson, is at IETF 90 in Toronto, Ontario, Canada this week. Follow along as she shares her findings with us on TeamARIN! Yesterday morning I attended the IEPG (Internet Engineering and Planning Group) meeting here at IETF 90. George Michaelson of APNIC gave an interesting presentation about Teredo (a tunneling technology that allows IPv6 capable hosts to use IPv6 over a IPv4 only connection). George’s slides are here. The great thing about his presentation is that he observed Microsoft doing exactly what they said they were going to do. They turned off their Teredo relays. It is clear in George’s graphs that the Microsoft Teredo relays have been turned off. The presentations about sunsetting Teredo are linked here:
