If you build it, they will come

by Leo Vegoda on August 25, 2010

As you would expect, most of ICANN’s external services, including this blog, are available over IPv6 as well as IPv4. And at the request of the ICANN Board, a regular comparative measure of IPv6 use at the ICANN and IANA websites has been provided to them for months.  The good news is that the trend […]


Situation in Haiti and the DNS

by Kim Davies on January 14, 2010

We have received a lot of communication concerning the devastation in Haiti, particularly its impact on Internet function and the .HT top-level domain. Here are the basic facts: We have been in contact with the administrators of .HT and they are alive and well, although understandably overwhelmed dealing with the tragedy there. Other ICANN fellows […]


IANA Business Excellence Explained

by Leo Vegoda on January 4, 2010

“Every day, in every way, I’m getting better and better” — Émile Coué de Châtaigneraie For the last couple of years the ICANN community and board have set staff a strategic priority of excelling in core operations. In the current draft strategic plan for 2010-2013 the emphasis has focused on the IANA Department, with a […]

Local communities … not just governments.

by Kim Davies on September 24, 2009

As ICANN staff, it is hard to avoid the news when your organisation is the subject of a hearing held by the United States Congress. This week we saw another such hearing, where the House Judiciary committee discussed the future deployment of new top-level domains. A number of people testified, including my colleague Doug Brent, […]


More IPv4 Used but Unallocated

by Leo Vegoda on July 30, 2009

Some IPv4 /8s have been used to number IP networks in an unofficial and improper way. That is, they have been used without being properly allocated and registered in a public Whois database. In most cases these networks are mostly private, used internally in their organization, and so the addresses are not seen in the Internet’s routing system. The organizations using these addresses have relied on the overall availability of IPv4 addresses so that there was no pressing need to allocate all of the /8s that IANA manages. With the decreasing IANA free pool of unallocated IPv4 addresses, it is now clear that every last one of them will ultimately be allocated to the RIRs.


A small gauge of diversity

by Kim Davies on June 18, 2009

In managing the root zone, recently we clarified some of the technical conformance criteria for the name servers top-level domain operators use. Before we put the adjusted criteria in place, we did some research to find out real world compliance against some of the metrics. One of the more interesting insights involved looking at network […]


Why the DNS is broken, in plain language

by Kim Davies on November 12, 2008

At ICANN’s meeting in Egypt last week, I had the opportunity to try and explain to various non-technical audiences why the Domain Name System (DNS) is vulnerable to attack, and why that is important, without needing a computer science degree to understand it. Here is the summary.


Which region is taking the lead in IPv6 deployment?

by Leo Vegoda on September 28, 2008

IPv6 is in the news because the mainstream media have started to pick up the fact that IPv4 will be fully allocated in the next two or three years. And IPv6 deployment is important if we want to keep the Internet growing sustainably.

So where is IPv6 deployment most evident? It?s a very difficult thing to measure. It is difficult to measure the amount of IPv6 traffic as so much of it is tunneled inside of IPv4. And anyway, tunneled traffic is probably from end users rather than ISPs, but we need ISPs to deploy IPv6 to allow the Internet to grow. So how can we see where ISPs are deploying IPv6 in their networks?


Every year there are new world events that see possible border changes and a restructure to the way the world’s countries and territories are configured. Think back to 50 years ago, and the world’s map was very different. There are literally a hundred countries that exist today that did not exist a hundred years ago. I wonder what country code the Ottoman Empire would have?

As these events occur, ICANN invariably receives requests to recognise new sovereign entities. In some cases we see very inaccurate press reports by “experts” on how country codes will be assigned. Thankfully, we have a very clear process for this that it is worth repeating.


Used but Unallocated

by Leo Vegoda on August 4, 2008

In February I commented about how we have been doing some research into the use of unallocated address space on the Internet.
