IPv6 Transition

Measuring World IPv6 Day - First Impressions

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...

IPv6 Shows a Pulse

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.

IPv6 Day a Couple of Days After

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.

8 Security Considerations for IPv6 Deployment

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.

RFC 1918 Address Space: Why It Was Needed then and How It Will Change in IPv6!

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...

Two Stage Filtering for IPv6 Electronic Mail

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.

How Many IPv4 Addresses Does the RIPE NCC Have Left?

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.

DHCP for IPv4 vs. IPv6 - What You Need to Know

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.

What is Internet Protocol Address Management?”

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.

IP Addressing in the New Age of Scarcity

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.
