Your error is seen by DNS Expert "dns.knowledgesharing.com is not listed in delegation data" and so it useless as NS for Internet's purposes. Internet queries the .com parents to find your NS's (the delegation data and glue records), it does not query your NS's for this info. >What I don't understand is why the registrars that we use (jumpdomain and >netsol) know of my name server by its hostname. because that hostname is registered by the registrant with the domain's registar. >Surely, at some point on the internet, my name server must be known by its >IP address? when a registrant registers/modifies a hostname, it is actually an A record ns1.domain.com A ip.ad.re.ss you must not change this ip in the zone data without first changing it with your registrar. >How would one move a name server to a completely new IP address if that >name server is known by its hostname? whois host.domain.com ... to see the entire record for the host, whihc is in fact entered to the parent NS as an A record. # whois dns1.knowledgesharing.com Whois Server Version 1.3 Domain names in the .com, .net, and .org domains can now be registered with many different competing registrars.
