I'm trying to set up new nameservers on HostGator. We already have NS1. and NS2. set up, but i need NS3 - NS6 also and there are only 3 slots available for name server assignments.
The other option is to use a different domain name, but the rest are hosted on Verio and I don't have any clue how to do it for a verio domain name. Does anybody have resources or information of any kind that will help me set up nameservers on verio (or more than 3 nameservers on hostgator)? I would greatly appreciate it.
EDIT
Let me clarify my situation. I have 3 servers. I own like 50 domain names that all belong to different clients. they are all hosted by verio, except for a single domain name that is used as our nameserver. So we have NS1.example.com and NS2.example.com, and those point to server 1. I need NS3 and NS4 to point to server 2, and NS5 and NS6 to point to server #3. We're splitting our hosting across the three servers. we'll probably have 15 or so websites on each, realistically. So I need to control DNS on the servers for each domain name. I don't want to do it from the registrar's zone file. Am i correct in assuming that I need nameservers to assign to the domain names? to point to the new servers?
