The NS record lists the name of a machine that provides domain service for a particular domain. The name associated with the RR is the domain name and the data portion is the name of a host that provides the service.
An NS (name server) record allows you to delegate a subdomain of your domain to another name server. The machines providing name service do not have to live in the named domain. There should be one NS record for each server for a domain. NS records for a domain exist in both the zone that delegates the domain, and in the domain itself.
There is fast link for ns lookup and check ns record: or (http://my-addr.com/ns/yahoo.com)

[www.domain.com] it's subdomain of [domain.com]. Thats why [domain.com] can exist but [www.domain.com] not exist and [www.domain.com] can exist but [domain.com] - not.
As usualy ns records don't exist for subdomain [www.domain.com], thats why on fail - you can try to do ns record lookup for domain (hostname) without 'www'
Search masks like '*.domain.com' are NOT allowed for ns record lookup, if it will be realy need pls write feedback to us.
