l.root-servers.net

IMPORTANT: Change of IP address

Notice that there was a change to the IP address of L.ROOT-SERVERS.NET,

The new IPv4 address for the server is:

199.7.83.42

This change was implemented in the root zone on 1 November 2007. It replaced the previous IP address of 198.32.64.12.

We encourage operators of DNS infrastructure to update any references to the old IP address, and replace it with the new address. In particular, many DNS resolvers have a DNS root "hints" file. This should be updated with the new IP address.

New hints files will be available at the following URLs once the change has been formally executed:

ftp://rs.internic.net/domain/db.cache
ftp://rs.internic.net/domain/named.cache
ftp://rs.internic.net/domain/named.root

It is expected that the old address will continue to work for at least six months after the transition, but will ultimately be retired from service.
