This is a feature / limitation of IP.  If you want to serve multiple
domains from the same webserver / mail server, most can be configured to
do this (IIRC these are 'vhosts' in Apache parlance).  With relaying /
proxying you may be able to offload soem of the processing to different
servers.  If you want to run multiple webservers you will need to run
them on different IPs or on different ports.

In the classical case you have one IP per guest.  Sharing IPs between
guests is also possible.
