We pick a.root-servers.net, one of the 13 root servers (1), and ask it about vmbook.com and learn that com is delegated to 13 name servers (2), so we ask a.gtld-servers.net where we learn that vmbook.com is delegated to two name servers, including dns2.tjgy.com (3), so we ask that one and get the following answer:
Vmbook.com is a domain controlled by two domain name servers at tjgy.com. Both are on the same IP network. Incoming mail for vmbook.com is handled by one mail server at google.com having a total of nine IP numbers. Some of them are on the same IP network. Vmbook.com has one IP number (66.220.4.148).
All of the about thirty domains that use the primary name server dns.tjgy.com use name server group 1 (example: tgpslideshow.com, aupas.net and bayhuo.net ). Worth noting is that most of the domains that use name server group 1 use the primary name server dns.tjgy.com.
The IPv4 number 66.220.4.148 only
There are more than two hundred domains that only use the IPv4 number 66.220.4.148.
