RFC974 says:

Each MX matches a domain name with two pieces of data, a preference
value (an unsigned 16-bit integer), and the name of a host.

RFC1034 3.6 defines an MX record as follows:


                MX              a 16 bit preference value (lower is
                                better) followed by a host name willing
                                to act as a mail exchange for the owner
                                domain.


Note `host name' not `address' in all these cases.
