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 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

To access this service DNS operators should update their hints files. In fact checking that you have the latest hints file on a regular basis is always good operational practice.

The latest hints files are available at the following URLs:


The root servers currently answering on IPv6 are:

A.ROOT-SERVERS.NET 2001:503:ba3e::2:30
F.ROOT-SERVERS.NET 2001:500:2f::f
H.ROOT-SERVERS.NET 2001:500:1::803f:235
