Talk your nameserver admin about adding in hostnames for each of
the aliases you've created. Then when someone on the Internet looks
up that hostname, it will return an IP address that points to your
machine.

In less capable OS's ;-), each network interface is normally
assigned only one or two IP addresses. If you need more, you either
physically add another NIC, or you hack the kernel into aliasing more
IP's to an existing interface. None of that is needed with FreeBSD,
however. Just use ifconfig to add as many IP's as you need, and to
the outside world it will appear as if you have many network
interfaces (thus "virtual interfaces", since you really only have one
physical interface).
