===================================

Query root servers for namserver information
=================

dig a.gtld-servers.net domain.com -t ns

or
nslookup
#server a.gtld-servers.ne
#domainname.com

=============

Note the root server only store information about the nameservers that the domain is currently pointed to. The nameservers then point to the dns server that host the dns zone file.
