You have an old DNS server: tallboy.example.org

You have a new DNS server: ns1.example.org

You have a domain, example.com, for which you want to swap the old DNS server with the new DNS using nsupdate.

NOTE: the domain is example.com

The NS servers are in example.org (different domains).

These are the commands you issue:

update delete example.com.      IN NS tallboy.example.org.
update add    example.com. 3600 IN NS     ns1.example.org.
send

Of note, you mention the domain first, the NS server second.

This took me a while to figure out tonight.

You will also want to update the records with your domain registrar.

  1. Congratulations on being the #1 google result for “nsupdate NS record”. Thought I recognized this name from somewhere. Oh, right, it’s from when I googled “nsupdate SOA record” and your gist was the #2 result.

    Crazy that they have such comprehensive docs but the section on nsupdate is just the manpage verbatim with no examples for SOA and NS records.
