DNS Root Server IP Address Change

This is just a quick note for you DNS operators out there.

Mark Andrews of ISC has notified the bind-announce mailing list that L.ROOT-SERVERS.NET has changed it’s ip address to 199.7.83.42. Mark’s suggested method for updating your BIND hints file is as follows:

$ dig ns . @a.root-servers.net > newfile

My configuration uses a file called db.root and the following stanza in my named.conf configuration file

zone "." {
  type hint;
  file "db.root";
};

Once your hints file is updated, the rndc reload command should load the new hints file. Here’s some additional information on how to configure rndc. Enjoy!
