We pick b.root-servers.net, one of the 13 root servers (1), and ask it about 74.ru and learn that ru is delegated to five name servers (2), so we ask a.dns.ripn.net where we learn that 74.ru is delegated to two name servers, including ns2.surbis.ru (3), so we ask that one and get the following answer:
A third of them use the two name servers ns and ns2.surbis.ru together, hereafter referred to as "name server group 1", (example: 86.ru, 53.ru and 2074.ru ).
Most of them point to IP group 1 (example: avto59.ru and 178.ru ).
The mail server smtp-in.w.rugion.ru only
There are about eighty domains that only use the mail server smtp-in.w.rugion.ru.
All of those use name server group 1 (example: 29.ru ). Worth noting is that half of the domains that use name server group 1 use only the mail server smtp-in.w.rugion.ru.
Most of them point to IP group 1. Worth noting is that a third of the host names that point to IP group 1 use only the mail server smtp-in.w.rugion.ru.
The two name servers ns and ns2.surbis.ru together
There are more than hundred domains that use name server group 1.
Half of those use only the mail server smtp-in.w.rugion.ru. Worth noting is that most of the domains that only use the mail server smtp-in.w.rugion.ru use name server group 1.
Half of them point to IP group 1. Worth noting is that a third of the host names that point to IP group 1 use name server group 1.
The two IP numbers 195.54.18.102 and 195.54.18.202 together
There are more than two hundred host names that point to IP group 1.
A third of those use name server group 1. Worth noting is that half of the domains that use name server group 1 point to IP group 1.
A third of them use only the mail server smtp-in.w.rugion.ru. Worth noting is that three quarter of the domains that only use the mail server smtp-in.w.rugion.ru point to IP group 1.
