We pick e.root-servers.net, one of the 13 root servers (1), and ask it about radcom.ir and learn that ir is delegated to three name servers (2), so we ask ns.irnic.ir where we learn that radcom.ir is delegated to two name servers, including ns1.parsihost.com (3), so we ask that one and get the following answer:
Three of the 14 host names that point only to the IP number 94.232.172.250 use name server group 4. Worth noting is that three of the domains that use name server group 4 point only to the IP number 94.232.172.250.
The name server ns2.parsihost.com
There are more than a thousands domains that use the name server ns2.parsihost.com.
