Nameserver (NS) records indicate which DNS servers are authoritative for a domain or subdomain. These are the nameservers that store the DNS records for the domain.
NS Records define the name of the zone’s domain nameservers. Since these types of records don’t include IP addresses, an A record needs to be established for the domain prior to adding an NS record to ensure the resolution request succeeds. For use with Secondary DNS, an A record would need to be established for both DNS servers.
Common Use Cases for NS Records
NS records are most commonly used when Secondary DNS is established. This allows a second set of DNS nameservers to be authoritative for the domain. These records are part of the “backup” solution that Secondary DNS provides by directing resolution requests to the alternate DNS server in the event one is offline
