Use Your Own Nameservers
From Lunarpages Web Hosting Wiki
Can I use my own nameservers?
The default nameservers for your Webmaster Reseller plan are:
But if you own yourowndomain.com and would like to make the nameservers your clients point their domains to be ns1.yourowndomain.com/ns2 this is something that can be done. In order to do this you will need to order two Dedicated IPs which can then be assigned to ns1 and ns2.
Note: It may take a few days for the dedicated IPs to be assigned. The nameservers cannot be created by us on the account until the IPs are assigned so please do not make any nameserver changes until we tell you to.
After the two Dedicated IPs are assigned you will need to set them up at your registrar. (See tutorials below.) If the domain is registered through Lunarpages we can assist you in setting this up.
Finally, log into WHM and click on Server Configuration > Basic cPanel/WHM Setup, enter the two new nameservers in the boxes (replace existing) and save your changes.
