The NS record type

The NS (nameserver) record type returns the nameservers responsible for the subdomain.

Examples #

Here, we query for NS records of the domain “example.com”. The result is two nameservers underneath “iana-servers.net”.

The IPv4 and IPv6 addresses of these two nameservers are also returned in the Additional section of the response, as indicated by the “+” character.
