This maybe a bit off topic in this group but refers to the original
posters question. NSIs whois server will give you a partial list of
domains hosted by a certain name server and registered through NSI. But
output is limited to 50 domains.

whois -h whois.networksolutions.com host NS1.ICOM.COM
[No name] (NS22604-HST)

...
whois -h whois.networksolutions.com server NS22604-HST
Aborting search 50 records found .....
...
