Adding NS Records for a Subdomain
Adding NS records for a subdomain will cause the subdomain to resolve with the configured name servers instead of the NS records at the zone’s apex.
Verifying the NS records are set up correctly
- Verify that your domain is delegated to DNSimple
- Verify the NS records are set up and we resolve them
dig @ns1.dnsimple.com NS subdomain.example.com
- Verify the trace actually goes to the domain
dig +trace subdomain.example.com
- Verify the TARGET NS are set up correctly
dig @ns.anotherdns.com subdomain.example.com
Name server propagation
It may take up to 24 hours for a name server change to propagate. The whois response is a good way to determine if the changes have been submitted properly.
