I would have to agree, not being a dig expert, I prefer nslookup.

server a.root-servers.net
Default Server:  a.root-servers.net
Address:  198.41.0.4

sec.gov.
Server:  a.root-servers.net
Address:  198.41.0.4

*** a.root-servers.net can't find sec.gov.: Non-existent host/domain


Not a good thing usually.

The a.root-server.net doesn't seem to be returning the NS records
for the GOV domain.  I'm not a 'dig' expert, so what am I doing
wrong?

Here is a normal DIG response for the COM top-level domain

Here is a DIG response for the GOV top-level domain, notice
it just returns an SOA record for the a.root-servers.net, no
NS records.

Here is a DIG response for a non-existant top-level domain,
same type of response as for the GOV domain.
