IPv6 Transition

Update on Assigning 32-bit ASNs

As mentioned in Assigning 32-bit ASNs published one year ago, 16-bit Autonomous System Numbers (ASNs) are becoming a scarce resource just like 32-bit IP addresses. In 2007, the Internet Engineering Task Force (IETF) addressed this scarcity by developing a new format: 32-bit AS Numbers (RFC 4893), which increased the supply of ASNs to four billion.

Measuring IPv6 - Country by Country

Some years ago a report was published that ranked countries by the level of penetration of broadband data services. You can find the current version of that report at the OECD web site. This ranking of national economies had an electrifying impact on this industry and upon public policies for broadband infrastructure in many countries. Perhaps this happened because there were some real surprises lurking in the numbers at the time.

Measuring World IPv6 Launch: Comparing IPv4 and IPv6 Performance

Following on from last year's measurements after World IPv6 Day, the RIPE NCC carried out active measurements on World IPv6 Launch on 6 June 2012. These measurements included latency measurements both on IPv4 and IPv6 from our vantage points to selected hostnames of World IPv6 Launch participants and other dual-stacked parties. We used these measurements to determine the performance of IPv4 versus IPv6 connections.

IPv6 and IP Convergence: Are International Treaties About to Govern the Internet?

Contributing to international telecommunications standards, not in the IETF but in a more august and imposing body, the ITU-T, part of the United Nations, was quite an experience. Still called CCITT in those days, it was formal and solemn; everybody was part of and sat with their national delegation, countries were aligned in alphabetical order; nobody spoke out of turn, every word was simultaneously translated in the three official languages of the time and we wore suit and tie.

Is IPv6 a Boon to Criminals and Foe to the FBI?

Declan McCullagh recently opined that the "FBI [and the] DEA warn [that] IPv6 could shield criminals from police." His post was picked-up relatively widely in the past few days, with the headlines adding more hyperbole along the way. So just how real is this threat? Let's take a look.

The Business Parallels Between IPv6 and DNSSEC

For two things that would seem to be completely unrelated there is an interesting parallel between IPv6 and DNSSEC. In both cases there is a misalignment of interests between content providers and service?providers. Content providers aren't highly motivated to deploy IPv6 because only a small proportion of users have v6 connectivity and even fewer only have v6. Service providers aren't anxious to deploy IPv6? because there isn't a lot of content on v6, and virtually none exclusively on v6 - so they don't expand the universe of interesting stuff on the web by deploying IPv6. Basically the same things could be said about DNSSEC.

Measurement Results from World IPv6 Launch

As announced on RIPE Labs we monitored the behaviour of a number of networks that participated in the World IPv6 Launch on 6 June 2012. For that, we looked at the full list of participating organisations as shown on the ISOC website and chose 50 websites from that list. We looked at 'interesting' sites and at geographic distribution. We also tried to find a good mix of networks that had IPv6 switched on already and those that didn't have IPv6 deployed at the time they registered on the ISOC web site.

Do We Need An IPv6 Flag Day?

In recent interviews about World IPv6 Launch I've been asked by several different people whether or not I think there needs to be some kind of a "Flag Day" on which the world all together switches from Internet Protocol version 4 (IPv4) to the version 6 (IPv6). I don't think a flag day is needed. World IPv6 Launch is just the right thing. It's worth looking at some previous flag-type days to get a better sense of why.

World IPv6 Launch: Now What?

World IPv6 Launch kicked off 6 June 2012 at 00:00 UTC. On this day, multitudes of website operators, network operators and home router vendors from all over the world have joined thousands of companies and millions of websites in permanently enabling the next generation Internet. They have done this by turning IPv6 support on by default in (at least some of) their products and services. This is a major milestone in the history of the Internet.

Best Practices for Implementing IPv6 and Avoiding Traffic Exposures

There has been a lot of discussion lately about the potential for IPv6 to create security issues. While there are definitely some security risks of IPv6 deployment, a carefully considered implementation plan can help mitigate against security risks. As we approach World IPv6 Launch tomorrow, I thought it prudent to share the below described incident that iDefense recently observed.
