Quick answer
At Netfirms, private nameservers such as ns1.example.com require registrar host/glue registration and matching DNS records. They are different from simply assigning existing nameservers to a domain.
Applies to
For an authorized domain owner with a supported reseller/DNS arrangement. Ordinary website customers can use the nameservers assigned to their service and do not need private nameservers.
Steps
- Confirm that your reseller or DNS service supports private nameservers. Obtain the exact hostnames and service-assigned IP addresses; two names do not by themselves provide independent DNS servers.
- Sign in to the current registrar for the parent domain. The older Netfirms video shows DNS > Private Nameserver. Find the current child-host, registered-nameserver or glue-record function, or ask that registrar for its equivalent.
- Register each intended nameserver hostname with its assigned address. Create the matching A/AAAA records in the authoritative DNS zone as required by the service.
- Verify that the DNS servers actually answer for the intended zones before changing a customer domain's nameserver delegation. Retain old settings until the change is accepted.
Check the result
Check both the parent/registry glue and the authoritative host records, then query each nameserver directly for the intended zone. A saved registrar form or A record alone is insufficient.
Troubleshooting and support
If the registrar rejects a hostname or the server does not answer, confirm parent-domain ownership, glue support and the assigned service addresses. Do not invent additional IPs or assume an ordinary cPanel login operates a nameserver.
If the problem continues, contact support from the account that owns the service. Include the domain, exact error, time and time zone, tool name, and a redacted screenshot. Keep passwords, private keys, cookies and private message content out of the ticket.
