IPv6 Transition

IPv6 Market Has Liftoff - Now the Hard Part Begins

Starting last week there have been a number of sensational headlines about IPv6 user adoption using adjectives and phrases like, "explodes", "skyrocketing" and "conquering the world". Nice to hear for sure but what does that mean to vendors of IPv6 gear or anyone else studying the market? more

IP Addresses and Privacy Sensitive Data - A Level Playing Field Needed

Reading Peter Olthoorn's book on Google (a link is found here), I ran into a passage on IP addresses. Where Google states that it does not see an IP address as privacy sensitive. An IP address could be used by more than one person, it claims. The Article 29 Working Party, the EU privacy commissioners, states that it is privacy sensitive as a unique identifier of a private person. It got me wondering whether it is this simple. Here is a blog post meant to give some food for thought and debate. I invite you to think about the question 'how private is an IP address'? more

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. more

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. more

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.  more

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. more

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. more

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. more

Vint Cerf: The Launch of a New Larger Internet

In preparation for the World IPv6 Launch tomorrow, Vint Cerf, Chief Internet Evangelist at Google, and a founding father of the Internet, discusses the next version of the Internet, and why we need it.  more

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. more

A Logical Place to Start the IPv6 Transition

The transition to IPv6 is top of mind for most service providers. Even in places where there are still IPv4 addresses to be had surveys we've run suggest v6 is solidly on the priority list. That's not to say everyone has the same strategy. Depending where you are in the world transition options are different -- in places such as APAC where exhaustion is at hand one of the many NAT alternatives will likely be deployed since getting a significant allocation of addresses is not going to happen and other alternatives for obtaining addresses will prove expensive. more

Business Case for IPv6 - Part 2

In my previous blog on the topic, I stated that the business case supporting the IPv4 roll-out in the late 90s was the Internet. Although IP depletion will slowly become a reality, the chances are that due to mitigating technologies such as NAT and DNS64, it may take quite a while before organizations in the developed economies will get serious about IPv6. So where should we look to find a business case for IPv6? more

Measuring IPv6 at the Network and the Customer Level

George Michaelson, APNIC's Senior Research and Development Scientist recently visited the RIPE NCC to collaborate on various research projects with his RIR colleagues. IPv6 measurements were one of the topics we looked at. Recent IPv6 statistics from the RIPE NCC show an accelerated uptake of IPv6 in Norway, both in terms of the number of allocated prefixes, and visible announcements in the routing system. more

Update on IPv6 Address Distribution in the RIPE NCC Service Region

At the recent RIPE Meeting we presented some IPv6 address distribution statistics that we would like to share with a wider audience. In the article below, you can find recent statistics on IPv6 allocations and assignments. The first image shows the number of IPv6 allocations the RIPE NCC made to LIRs in each quarter, starting in 2008... Each year is depicted in a different colour, the last one showing the number of allocations made in Q3 2012. more

Apple Under Criticism for Back-Pedaling on IPv6 Support

Apple Computer's AirPort Utility, Version 6.0 was criticized this week at the North American IPv6 Summit for no longer being compatible with IPv6. The previous Version, 5.6, offered IPv6 service by default. "Comcast, for example, is urging its subscribers that are interested in using IPv6 not to upgrade to AirPort Utility Version 6.0 if they use the OS X Lion operating system because of incompatibilities with IPv6." more
