We pick a.root-servers.net, one of the 13 root servers (1), and ask it about ns4.7y-al6rb.com and learn that com is delegated to 13 name servers (2), so we ask l.gtld-servers.net where we learn that 7y-al6rb.com is delegated to two name servers, including sell.internettraffic.com (3), so we ask that one and get the following answer:
All of the several thousand of domains that use the primary name server ns1197.ztomy.com use name server group 1 (example: iklangratis.org, farm.y3y3.info and eshkin.com ). Worth noting is that all of the domains that use name server group 1 use the primary name server ns1197.ztomy.com.
The two name servers ns1197 and ns2197.ztomy.com together
There are several thousand of domains that use name server group 1.
