If I have a name server, let's say ns1.mydomain.com, that is already registered and it's ip is 1.1.1.1, how do I go about changing it's ip so that it is 2.2.2.2 using enom's system? I see where to create nameservers and check their status, but I don't see any where to delete them or edit them.

I just became an eNom reseller today - checked their FAQ and forms and it says to contact: service@enom.com

This might change once I register a few name servers there, but to date my account has zero domains.

The eNom experts here might be more helpfull

You need to contact enom if you would like to change the IP of an already registered nameserver. You can contact Billy Knott (Technical Support Manager), he will certainly help you.

I have the same experience, Marty. :)

No, you cannot change those NS. You have to email billy@enom.com

Hope this helps. :)
