Creating Nameservers

[Gumby]

I am having difficulty creating my own nameservers on a domain name registered through registry rocket. I am getting the following error message:
*****Errors modifying nameservers: Nameserver ns1.ultrahost.net cannot be registered*****

What am I doing wrong here?

thankyou,
Steve

A name server domain - with r-rocket?

It can be done - but if you know the parent enom reseller try to get it to a full enom account first!

Do you have the host IPs available - becuase it's even harder to modify a name server once it's created.
