Re: can't change supposedly dynamic IP address

How can I spoof the MAC address? I see the option of "Clone your MAC IP" from one of my router's menus but what's the advantage of cloning it if the ISP is already reading it & basing the IP address on it? Thanks for your answer.

Basically, if you clone your MAC it makes the router show Mediacom a different MAC address so then you will get a new IP.

I've already tried cloning the address & it didn't change afterwards. In any case, isn't that really the opposite of spoofing?

I found instructions to spoof from IronGeek.com. I don't have a problem with editing the registry as I just back it up beforehand, but do these instructions look valid to anyone here who know how to spoof Mac addresses?

In XP you can use the regedit to edit the registry from a GUI or the reg command to edit it from the console, I'll be using regedit. Information on all your NICs can be found the registry key HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\ Class\{4D36E972-E325-11CE-BFC1-08002bE10318}\ . Under this key you will find a bunch of sub keys labeled as 0000, 00001, 0002 and so forth. We can assume any MAC address we want by finding the key that controls the NIC we want to change, putting in a string value called "NetworkAddress" and setting it to the MAC address we want to use formatted as a twelve digit hex number (example: 000000000001). To find out which key is which we can search through them for the value "DriverDesc" until we find the one that matches the NIC we wish to alter. After you set "NetworkAddress" to the address you want just restart the NIC by disabling it then enabling it (or in the case of PCMCIA cards, just eject and reinsert). You can confirm the MAC address change by using the "getmac" or "ipconfig /all" commands.
TIA.

It needs to be done on the router, not your computer.
