Private Nameserver:
For example your company domain is resellerdomain.com. Hence you have to create your nameserver with registrar using the following settings
ns1.resellerdomain.com - 74.200.80.235
ns2.resellerdomain.com - 207.58.130.53
Once completed, you may change your client's nameserver to use your private nameserver.
Shared Nameserver:
If you wish to use our white labeled nameserver, use the following nameserver on all of your domain
ns1.adminz.net - 74.200.80.235
ns2.adminz.net - 207.58.130.53
