If you want IP addresses you can connect to the Internet with, then there are no "free" ones. You'll have to get officially registered addresses from your ISP or from the InterNIC. If you want addresses to use on a private network that does not connect to the internet, there are addresses set forth in RFC1597 for that purpose. Those are: The 256 class C addresses 192.168.0.x - 192.168.255.x The 16 class B addresses 172.16.x.x - 172.31.x.x The class A address 10.x.x.x (you can retrieve the document from http://www.internic.net/rfc/rfc1597.txt). Those addresses are not used on the Internet, so if you use them on an internal network connected through a firewall that does address translation you'll have no real problems. Hope that helps, Nadav
