1. Log into the Domain Management Interface
2. Click on the Manage Name Servers section
3. Click on the link at the bottom of the page that says If you want to create or modify a name server which is based on {your domain} click here
4. Change the old host name to the new one
5. Click Save Configuration

This change will be automatically applied to all domains using this name server.

Note that this will only rename name servers within the same Registry.   This means that if you rename a .COM nameserver, it will only update COM/NET domains as they are run by the same Registry (operated by Verisign).  Renaming a .COM/.NET name server will not update .ORG domains! (.ORG Registry is operated by the Public Interest Registry)

If all you need to do is change DNS on your domain so that you are hosting with a different company, look into at changing your DNS/name server.

Only the domain owner can create a nameserver host record. This can be done via the Domain Management Interface.

Nameserver IP addresses are not required by most Registries and are not displayed by our system. This does not affect the operation of the nameserver.

BEFORE YOU PROCEED PLEASE NOTE THE FOLLOWING:

This option is usually only done by Internet Service Providers, Web Hosting companies or experienced system administrators on behalf of domain owners. Please ensure that the server hostnames you are creating are running DNS/BIND software in order for the name servers to work properly.

IF YOU ARE NOT CERTAIN OF WHAT YOU ARE DOING PLEASE PROCEED WITH CAUTION, AS YOU MAY CAUSE YOUR DOMAIN TO STOP FUNCTIONING CORRECTLY. IF YOU MAKE A MISTAKE IT CAN TAKE UP TO 48 HOURS FOR THE CORRECTION TO PROPAGATE ACROSS THE INTERNET!

To begin managing name servers which are based on your domain name:

1. Log into a Domain Management Interface
2. Choose Name Servers from the options at the top of the page.
3. Scroll to the bottom of the page where it says If you want to create of modify a name server based on domain name, click here.
4. Click there
5. You will see a set of boxes, one of which will accept data.   The second box will not be editable, and will display your domain name.  Choose a nameserver prefix and type it into the box.   PLEASE NOTE: DO NOT USE WWW or MAIL AS A NAME SERVER PREFIX! NS1 or DNS1 would be a good idea. The full contents of these boxes (eg. DNS1.EXAMPLE.COM) will be the name of the new name server. In the IP box, you will need to type in the IP address of your domain’s name server.
6. Click on the Create Nameserver option

You should see a note that says Name server DNS1.EXAMPLE.COM is registered.   This means the registry knows of the existence of your name server.   It will take 24 – 48 hours before your nameserver info propagates to the rest of the world.

A handy tool to help with debugging of domain/DNS issues is http://www.dnsreport.com .   If it says your domain is not listed in the root servers, wait 24 hours to allow time for the root servers to refresh.
