NS (name server) resource record

NS (name server) resource record

NS lists a name server responsible for a given zone. The first ``name'' field lists the zone that is serviced by the listed name server. There should be one NS record for each name server for the zone, and every zone should have at least two name servers, preferably on separate networks. Here is an example of a name server record:

   {name}  {ttl}   addr-class   NS   Name servers name
   @               IN           NS   volga.mynet.COM.
The ``@'' character specifies the current origin. The address class is IN (Internet addresses), and the record type is name server (NS). The record uses the default TTL (time-to-live) value. Here, the record-specific data is the identity of the name server.
