We pick j.root-servers.net, one of the 13 root servers (1), and ask it about xvideos.pe and learn that pe is delegated to three name servers (2), so we ask sns-pb.isc.org where we learn that xvideos.pe is delegated to two name servers, including ns2.xvideos.pe (3), so we ask that one and get the following answer:
The two name servers ns1 and ns2.xvideos.pe together
There are one domains that use the two name servers ns1 and ns2.xvideos.pe together, hereafter referred to as "name server group 2".
All of those point only to the IP number 66.85.175.18. Worth noting is that one of the host names that point only to the IP number 66.85.175.18 use name server group 2.
All of them use only the mail server xvideos.pe. Worth noting is that all of the domains that only use the mail server xvideos.pe use name server group 2.
The name server ns1.xvideos.pe
There are one domains that use the name server ns1.xvideos.pe.
All of those point only to the IP number 66.85.175.18.
There are one domains that only use the mail server xvideos.pe.
All of those point only to the IP number 66.85.175.18. Worth noting is that one of the host names that point only to the IP number 66.85.175.18 use only the mail server xvideos.pe.
All of them use name server group 2. Worth noting is that all of the domains that use name server group 2 use only the mail server xvideos.pe.
The IP number 66.85.175.18 only
There are seven host names that point only to the IP number 66.85.175.18.
