DNS delegation of ctbfiber.com updated: May 21, 2013 12:02:12 AM
We pick b.root-servers.net, one of the 13 root servers (1), and ask it about ctbfiber.com and learn that com is delegated to 13 name servers (2), so we ask a.gtld-servers.net where we learn that ctbfiber.com is delegated to two name servers, including ns14.zoneedit.com (3), so we ask that one and get the following answer:
Ctbfiber.com is a domain controlled by two domain name servers at zoneedit.com. Both are on different IP networks. Incoming mail for ctbfiber.com is handled by seven mail servers at googlemail.com and google.com having a total of 58 IP numbers. There are 33 duplicated IP numbers. Some of them are on the same IP network.
