At-Large Summit – an Overview

by Nick Ashton-Hart on February 19, 2009

The Mexico City meeting is a landmark for At-Large. For the first time, the whole At-Large community will be meeting together face-to-face in the ‘At-Large Summit’. About 90 representatives of the At-Large membership of organisations (called “At-Large Structures”) are already confirmed. Mexico City meeting attendees will be able to spot them easily, as each will have a ribbon indicating their status as a Summit delegate attached to their ICANN meeting badges.

It is being held 28 February through 5 March, at the Sheraton and also at the nearby Melia Mexio Reforma hotel.

All ICANN staff, board members, and community members are invited and encouraged to attend the sessions, all of which are open to everyone.

Conflicker, DNS Security and what ICANN is doing about it

by Greg Rattray on February 14, 2009

Over the past two months the Internet has faced yet another threat to its security and one that directly involves the Domain Name System.

The Conflicker/Downadup worm infects computers running Windows operating systems variants. The infected computers can be remotely controlled (i.e. forming a botnet) and the infection propagates through a number of different routes. The worm has been estimated as infecting as many as 10 million hosts and data from the security community indicates the number is at least 1.5 million. One mechanism the worm’s code uses to enable control is to download commands by accessing specific date-based domain names.

{ 5 comments } goes IPv6

by John L. Crain on December 15, 2008

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


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.


Remembering Jon: Looking Beyond the Decade

by Vint Cerf on October 1, 2008

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.


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.

Ghosts of Root Servers Past

by David Conrad on May 19, 2008

As noticed by some in the Internet network operations community, at the beginning of May an odd event occurred as ICANN ended DNS service on the IP address formerly associated with L.ROOT-SERVERS.NET (“L-root”). Specifically, as ICANN turned off the DNS service at the address formerly used by the L-root, (and the routing announcement by ICANN for, DNS root queries sent to that address instead of the new L-root address ( continued to be answered.
