The following will NOT result in a valid lookup:
somehost -> a.b.c.d; a.b.c.d -> otherhost; otherhost -> p.q.r.s
This implies that I cannot run a mail server on a cable modem. This is
uncool. The reason is that the a.b.c.d -> otherhost which typically
doesn't map to anything.
You have to allow for the case where the a.b.c.d is administratively
controlled by someone other than the system administrator.
