We pick d.root-servers.net, one of the 13 root servers (1), and ask it about ns2.muridhosting.com and learn that com is delegated to 13 name servers (2), so we ask j.gtld-servers.net where we learn that muridhosting.com is delegated to two name servers, including ns2.muridhosting.com (3), so we ask that one and get the following answer:
All of the three domains that only use the IPv4 number 50.116.108.236 are under the tld "com".
The primary name server ns1.motivation411.com only
All of the five domains that use the primary name server ns1.motivation411.com use name server group 1. Worth noting is that all of the domains that use name server group 1 use the primary name server ns1.motivation411.com.
The two name servers ns1 and ns2.motivation411.com together
There are five domains that use name server group 1.
All of those use the primary name server ns1.motivation411.com. Worth noting is that all of the domains that use the primary name server ns1.motivation411.com use name server group 1.
Three of them point only to the IP number 184.173.10.147.
The name server ns2.muridhosting.com
All of the ten domains that use the name server ns2.muridhosting.com use the two name servers ns1 and ns2.muridhosting.com together, hereafter referred to as "name server group 2".
The two name servers ns1 and ns2.muridhosting.com together
Eight of the ten domains that use name server group 2 use the primary name server ns1.muridhosting.com.
