Multiple sites on ONE IP Address (ISS)?

Hello,

I have bought a new Windows 2003 Web Server.

It has ONE static IP address with one domain, domain.com.

domain.com works fine.

How do I go about getting domain2.com to work? Do I need an extra IP
address (one IP address per site?) or can I configure many domain names to
work on the one STATIC IP?

I have read the help file but it is not clear to me.

Any help appreciated!!!

Regards,

Gary.
