What is a DNS NS record?

NS stands for ‘name server’ and this record indicates which DNS server is authoritative for that domain (which server contains the actual DNS records). A domain will often have multiple NS records which can indicate primary and backup name servers for that domain.

Example of an NS record:

example.com record type: value: TTL
@ NS ns1.exampleserver.com 21600
