I’ve previously written about the problem with IPv4 /8s which have been used to number IP networks in an unofficial and improper way.
The problem is that the unofficial usage makes it more difficult for ISPs to bring these addresses into use when they are officially allocated and so less desirable. But we have to allocate [...]

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.

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 diversity. [...]

Last week IANA processed a request to add AAAA records for one of the thirteen DNS root-servers.

L.root-servers.net, operated by ICANN, became the seventh of of the root servers to have it’s IPv6 address records (AAAA) added into the DNS root-zone. The addition of IPv6 service is part of ICANN’s ongoing commitment to act as a leader in enabling IPv6 services throughout the DNS.

The new IPv6 address is 2001:500:3::42

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.

A decade has passed since Jon Postel left our midst. It seems timely to look back beyond that decade and to look forward beyond a decade hence. It seems ironic that a man who took special joy in natural surroundings, who hiked the Muir Trail and spent precious time in the high Sierras was also deeply involved in that most artificial of enterprises, the Internet. As the Internet Assigned Numbers Authority (IANA) and the RFC editor, Jon could hardly have chosen more polar interests. Perhaps the business of the artificial world was precisely what stimulated his interest in the natural one.

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.
