We pick f.root-servers.net, one of the 13 root servers (1), and ask it about mexicoweb.com.mx and learn that mx is delegated to six name servers (2), so we ask x.mx-ns.mx where we learn that mexicoweb.com.mx is delegated to two name servers, including ns52.1and1.com (3), so we ask that one and get the following answer:
Mexicoweb.com.mx is a domain controlled by two domain name servers at 1and1.com having a total of four IP numbers. Some of them are on the same IP network. Incoming mail for mexicoweb.com.mx is handled by two mail servers at mexicoweb.com.mx and 1and1.com. Both are on the same IP network. Mexicoweb.com.mx has one IP number (74.208.113.29), which also has a corresponding reverse pointer.
