N
NS record
A type of resource record in a zone file that identifies the name servers that are authoritative for a zone. A zone file contains one NS record for each of the zone’s own authoritative names servers. It also includes an NS record for each subdomain that has been delegated to other authoritative name servers. If a subdomain’s authoritative name server resides within the subdomain’s namespace, the zone file must include a glue record that provides the name server’s Internet Protocol (IP) address.
