trrsf.com.
trrsf.com.
(ns5,ns3,ns4).terra.com.
We pick m.root-servers.net, one of the 13 root servers (1), and ask it about trrsf.com and learn that com is delegated to 13 name servers (2), so we ask m.gtld-servers.net where we learn that trrsf.com is delegated to three name servers, including ns5.terra.com (3), so we ask that one and get the following answer:
Trrsf.com is a domain controlled by four domain name servers at terra.com and terra.com.br having a total of four IP numbers. There are two duplicated IP numbers. Two of them are on the same IP network.
