Yes, but they usually insist that there is also second nameserver in another netblock
You can easily check with
dig whether your nameserver has been adopted into the domain name system:
Code:
$ dig +norecurse -t ns SNIPER-UNIX.ORG @a.root-servers.net
; <<>> DiG 9.3.4 <<>> +norecurse -t ns SNIPER-UNIX.ORG @a.root-servers.net
; (2 servers found)

Here we do a non-recursive query at the
a.root-servers.net for the nameserver of your domain.
The answer is an referral, or "I don't have that info, but the following nameservers can help you further".
Then you ask one of those they referred: 199.19.56.1
Code:
$ dig +norecurse -t ns SNIPER-UNIX.ORG @199.19.56.1
; <<>> DiG 9.3.4 <<>> +norecurse -t ns SNIPER-UNIX.ORG @199.19.56.1

This returns a SOA record instead of a proper answer.
You can repeat this for the others
