You can register your name servers under your account's Domain Host Summary section.
Registering your name server IP addresses allows you to define a name for your server based on your domain name.
You can register any hostname you wish, in the format: host.domain.tld example: "nameserver1.yourdomain.com"
If you understand what is involved and have made the necessary preparations, please follow the steps below to register your name servers.
First, log into your customer account: Go to the Go Daddy Account Login Page. Log in using your account username (which may be the same as your customer number) and password. Once logged in just follow these steps:
Go to Domains >> My Domains Click on your domain you'd like to set up private nameservers for
Click on View/Modify Detail under 'Host Summary' on the bottom left
For Host Name 1: you will input ns1 in the box
For Host Name 2: you will input ns2 in the box

After you've registered the private nameservers, you can now set all of your domain names to use the nameservers you just registered.
