Custom Nameservers can be Created by you at your Domain Registrar. Your Customers will be able to use you Custom Nameservers when they update their own Nameservers to connect to the Server. This will make the Reseller Service White-Labeled. Your Customers will not know that you are a Reseller.
If you already have a Domain you have to create your Reseller Custom Nameservers. Simply log in to your Account at the Domain Registrar and add two A records for your Domain in the DNS Management Section. You have to add the IP of our Server to your Custom Nameservers:
18.104.22.168 for the First Nameserver
22.214.171.124 for the Second Nameserver
You can create any Subdomain you want: a few examples:
If you buy your Domain from us then the Nameservers are configured automatically to Point to the Server your Website is located at! Keep in mind that Custom Reseller Nameservers still have to be Created!
