How do I get a different IP address? Comcast High Speed Internet FAQ| Because of the way DHCP works, it is possible to change your IP address simply by changing your MAC (media access control) address. Most routers have a MAC clone function, which is particularly well suited for letting people who’s ISP registers them by the modem and NIC’s mac use the router, but it can also be used to change the MAC quickly and effectively. Keep in mind that after changing the MAC of your NIC, you will need to restart your modem to clear it’s CPE MAC Address table. Most NIC's also offer a MAC cloning function similar to that of a router that can be accessed through device manager->Your NIC->Properties->Advanced->Locally Administered Address. Change the value to a 12 digit long hexadecimal code and restart your computer. Some NIC's won't let you change the MAC, in which case »www.klcconsulting.net/Change_MAC_w2k.htm has some very useful information including a program that can allegedly change the MAC “regardless of whether manufacturers allow this option or not”. *This FAQ is based on user knowledge from a volunteer core of BroadbandReports' members.
