The dig from com's nameservers got nxdomain as well. As you see here,

$ dig datafarm.net @a.gtld-servers.net

nxdomain means this domain (zone) not existing, whether it's A record or 
the zone itself. if the zone exists but lacks A record, the status 
should be 'NOERROR'.

What confused me is that since domain is registered in the registrar, 
they should put a glue in com's nameservers. hence com nameserver would 
not return 'nxdomain' but a reference instead.

BTW, I found there are many cases like the domain 'datafarm.net'. for 
example, 'netfirm.net' behaves the same.

Thank you.
