Yes they are. With RAM you can set a particular IP for a particular port,
and you can also set a particular user to be the only one with access to
that port. It would be OK if I had a few hundred users that required
looking after in this specialist fashion, but most just dial up and don't
care what IP or port they get.

Only if you told them to dial a certain number, you can't allocate an IP to
a certain user.
