IANA Introduces AAAA Record For K-root

5 February 2008 - On 4 February 2008, at around 17:00 (UTC), IANA introduced AAAA records for six of the root servers in the root server system. One of these servers is the K-root, k.root-servers.net (2001:7fd::1), which is managed by the RIPE NCC. This change allows the root zone to be queried over IPv6.

The K-root IPv6 prefix is currently anycast from the two global nodes, located in Amsterdam and Miami. The introduction of the AAAA records went smoothly, and we are monitoring the query rate and pattern. We are also collecting more detailed information for future analysis. 

More information about AAAA records in the root zone is available on IANA website.
