We pick b.root-servers.net, one of the 13 root servers (1), and ask it about facebook.com.bo and learn that bo is delegated to two name servers (2), so we ask auth100.ns.uu.net where we learn that facebook.com.bo is delegated to two name servers, including v0.quientienemail.com (3), so we ask that one and get the following answer:
Facebook.com.bo is a domain controlled by one domain name server at com.bo. Incoming mail for facebook.com.bo is handled by seven mail servers at googlemail.com and google.com having a total of 61 IP numbers. There are 24 duplicated IP numbers. Some of them are on the same IP network.
