By default, virtual servers created by this reseller will have the same nameservers in their BIND configuration as every other domain. However, because resellers often want to make it appear as though they are running their own server, they may not want your nameserver hosts to appear in the domains they create.

This field allows you to enter custom nameserver hosts that will be used as the `NS` records in any domain the reseller creates. Make sure that they already exist in DNS, and are being used by whatever registrar the domains are registered with.
