This application is useful for gathering address information about hosts in the network. It can be used to query the Internet domain name service (DNS) for specific information about hosts (mail exchanger records [MX]; IP address [A]; canonical names [CNAME]; etc.). If you have an IP address, you can get a canonical name back for the address. If you have a canonical name, you can get an IP address. Another extremely useful feature is the ability to get a listing of hosts which serve mail exchange [MX] functions for a specific domain.
