Linux / FreeBSD: Multiple IP Addresses on One Interface
Q. Can one Linux / BSD system respond to multiple IP address on a single Ethernet interface? I need to run multiple web sites and mod_ssl with a single server. How do I configure my box for multiple IP address?
A. Linux / UNIX and BSD like operating systems supports multiple IP address on a single interface using a feature called ip aliasing. You can add extra IP addresses with the ifconfig command. However, I recommend modifying configuration files so that operating system remember all ips after reboot.

Hi,
it appears that You don’t have to have multiple ip’s to achieve this.You can do pretty much the same using TLS Extensions.Take a look:
