mx.

We pick c.root-servers.net, one of the 13 root servers (1), and ask it about mx-ns.mx and learn that mx is delegated to six name servers (2), so we ask e.mx-ns.mx and get the following answer:
Mx-ns.mx is a domain controlled by six domain name servers at mx-ns.mx themselves having a total of seven IP numbers. All seven of them are on different IP networks. Incoming mail for mx-ns.mx is handled by two mail servers at nic.net.mx. Both are on different IP networks.
