I disagree, it is not pointless.
Trying to remember someone by ip address (as you
might see them in logs or on IRC for example) is rather irritating, as
well as finding out where that perosn originates from.
Secondly if your MTAs were correctly configured then if it doesnt have
reverse DNS it would drop the connection.
Reverse DNS is usefull, but it should be managed, as mentioned, by
automated processes including dynamic updates from autoconf requests etc.
Having reverse DNS for privacy addresses however, is kindof stupid
because it curcumvents the whole point of the changing address for
That said, dead:cafe:beef:b00b makes half the worlds uses for reverse
DNS redundant :)
