Hi,
TL;DR: I too find it a little odd that whois says this domain is
reserved but
querying the DNS shows that it isn't there at all as I would
usually expect just the NS records to be present in the containing
zone. I can only assume that this registrar allows for registered
zones to not be published at all if one wishes. The whois is
authoritative for what is available to register; the DNS is
authoritative for what you can globally query.

This is the dns info from registry nameserver:
In future it would help if you showed what actual query you are
doing with "dig". From the output I can piece together that you did
something like:
$ dig datafarm.net
or
$ dig -t s datafarm.net
but assuming that indeed is what you did, it does not actually "ask
the registry nameserver".
We can see from your output that you got a response from:
;; SERVER: 10.160.0.1#53(10.160.0.1)
which is probably a resolver on your local network. So that answer
you got may have been from cache.
We can see from your output that you ended up (either implicitly or
explicitly) asking for an A query:

;datafarm.net. IN A
However the best record to use when trying to see if a domain exists
i*in DNS* is an SOA ("Start of Authority"). It should show where the
domain delegation happens. It's basically the details for the DNS
zone.

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.
