localhost at localdomain is not really a valid hostname in a networked
environment. Comcast has strict internal guidelines requiring unique
hostnames thoughout their network. They have set up their DHCP servers
to force a unique hostname whenever they find a machine without one
(either no name at all or one that is currently in use). I'm not sure
which category they group localhost in, but since customers are not
allowed to use it the distinction is mute.
