Any host which is on more than one network interface (for example a
firewall or a router) will have more than one IP address. It may also
have more than one hostname. Routing determines which interface is
used for any given packet. If you have a Virtual Private Network your
virtual IPs will be different from your physical IPs, and routing may
still be needed, but there may only be a single physical interface.
There are many other reasons why multiple IPs might exist for a single
host, and a few reasons why a single IP might be used by several hosts. :)
