Change modem IP address?

I have Comcast cable. My IP reports as a Comcast cable ip address. Which is 24.18.2xx.xx
Do you have a software to change the modem IP?

If you have a router hooked up there is an easy way to change your internet IP.

Comcast gives you an IP and remembers your IP by its mac address. So in the router it should support mac address spoofing. It allows you to make your own mac.

So change the mac address, then unplug the power to the cable modem and back in. When it comes up it will see the new mac and give you a new ip  :wink:

Hello again.
I check the router, it has MAC address. When I change router MAC address, I cannot connect to the Internet.
This is my default MAC: 00:24:b2:d5:47:e1
I change it to: 00:24:b2:d5:47:e2
It won't connect. Do I need to do anything else?

Restart the cable modem. It only gives out one ip at a time. So unplug the power and back in after you change the mac to get a new ip  :wink:
