The RIPE NCC took active measurements of World IPv6 Day participants before, during and after World IPv6 Day (in cooperation with CAIDA). We selected 53 participants and performed periodical A and AAAA DNS lookups and HTTP fetches from 40 servers worldwide. For HTTP, we fetched data over IPv4 and IPv6. These provide important control points... more
On World IPv6 Day IPv6 showed a pulse! However faint that global pulse may have been, our network showed at least some form of IPv6-life occurred on that day. Long supporters of IPv6, with a significant global DNS footprint handling extremely large volumes of global traffic we, at CommunityDNS, were curious on what may result through an organized focus on the use of IPv6. more
June 8th IPv6 World day came and went without any major glitches, let alone disruption of the internet, and witnessed varying traffic fluctuations depending where on the net observations were made. From a Tata Communications AS6453 perspective, a global tier 1 IP wholesale network, data gathered by a number of probes gave an interesting pulse on what happened in some major international arteries of the internet. more
Feb. 3, 2011, came and went without much fanfare, but it was a milestone for Internet stakeholders, whether they knew it or not. On that Thursday, the last available IPv4 addresses were allocated by the Internet Assigned Numbers Authority (IANA). Though some Regional Internet Registries (RIRs) have a reasonable inventory of IP addresses that could last another year or two, the days of "new" IPv4 address allocations are largely over. more
Recently, my firm has seen a lot of interest come from Enterprises seeking IPAM/DNS tools. We predicted that IPv6 adoption and the need for automation software/tools would follow the Internet ecosystem's supply chain starting with Service Providers consisting of ISPs, I/PaaS, ASPs, then content providers (mostly a service really), then Enterprises, followed by SMBs & Consumers. While good for business, it has also forced us to revisit and think thru many TCP/IP protocol standards... more
I'm a guest at the MAAWG conference in San Francisco this week and several people have now mentioned to me the problem and the opportunity of anti-spam e-mail filtering for IPv6. Tomorrow is World IPv6 Day but since a bunch of the pieces have clicked together in my head I'll post this a day early. more
Since IANA ran out of IPv4 addresses, people are increasingly aware of how short the remaining lifetime of IPv4 is. With World IPv6 Day taking place this week, the issue has come into even sharper focus. Since March 2011, the RIPE NCC has been publishing the size of its pool of available IPv4 addresses. All five Regional Internet Registries (RIRs) regularly publish the status of their IPv4 address pools. In the image below, you can see how the number of IPv4 addresses in the RIPE NCC pool changes over time. more
Dynamic Host Configuration Protocol (DHCP) is a protocol intended to enable machines (servers, game consols, etc) wishing to be "online" the ability to request Internet Protocol information from a DHCP server automatically. ... In this article we will begin to outline some of the fundamental differences between DHCPv4 and DHCPv6, explore historical uses of DHCPv4 and how those concepts will adapt/change in IPv6. more
The number of web-based devices is expanding at an exponential clip, virtualization is making a very static environment dynamic, and now with the exhaustion of IPv4 and the oncoming complexities of IPv6 network operators must reevaluate what IP Address Management (IPAM) really is. The goal of this post is to define the various functions that make up IP Address Management. more
This is the prepared opening statement given on behalf of Depository, Inc. at the panel discussion "IP addressing in the new age of scarcity" in the context of Internet governance and public policy at the Global Internet Governance: Research and Public Policy Challenges for the Next Decade Regional Conference held at the American University School of International Service on Thursday, May 5th, 2011 between 11:00 a.m. to 12:15 p.m. with Prof. Milton Mueller moderating and on the panel as well was John Curran, President and CEO of ARIN and Michael Froomkin, Professor of Law, University of Miami School of Law. more
