We pick f.root-servers.net, one of the 13 root servers (1), and ask it about cnr.ir and learn that ir is delegated to three name servers (2), so we ask ns.irnic.ir where we learn that cnr.ir is delegated to two name servers, including ns1.bijax.org (3), so we ask that one and get the following answer:
The two name servers dns21 and ns21.webvillage-dns.com together
There are three domains that use name server group 1.
All of those use only the IPv4 number 62.60.138.223. Worth noting is that three of the domains that only use the IPv4 number 62.60.138.223 use name server group 1.
All of them point only to the IP number 62.60.138.223.
The IPv4 number 62.60.138.223 only
Three of the four domains that only use the IPv4 number 62.60.138.223 use name server group 1. Worth noting is that all of the domains that use name server group 1 use only the IPv4 number 62.60.138.223.
