Buxtyy wrote Okay chill, i was wrong. I was pointing out though it isn't, or isn't meant to be as easy as changing an IP address. And anyway changing MAC Addresses wouldn't have any affect on which IP is assigned by the ISP.

actually its been known for quite some time that the mac on your router on cable based ISP's with dynamic ip setups do use your routers mac to assign IP's its a form of sudo static assigning that has been in use since 2004ish.
as you can see even the xbox modders have figured that out [ Register or Signin to view external links. ]

the reason that changing the router's MAC to get a new ip works is cause the node that your neighbor hood is on has a Gateway and a DHCP server that assigns IP leases based on the router's MAC so if you change the MAC and reboot the modem the DHCP server will see that the IP that the modem was using is still technically assigned and that the modem is using a different Router as far as it can tell and at which point the DHCP server will issue a different IP to your modem while still leaving the other one in a "leased" state.

also MAC changing is designed to be as easy as changing a local ip. hence why when you right click a network adapter and select properties you get a option to change the MAC as well as the Local IP within the same menu.

Oh that might be why then, i've never had cable its not as common in the UK as DSL. I wasn't referring to the routers MAC, just the one in a clients system.

However i've never seen the option to change a MAC address on windows or mac.

Yea DSL is usually static so you have to call your isp and say you are being stalked online and dont know what to do. or just demand to be issued a new ip though they sometimes charge for it. on the bright side DSL modems are easier to spoof but they are still limited to the speed's you can unlock cause they are still DSL

Linux Ubuntu is
sudo apt-get install macchanger
macchanger wlan0,eth0 "new mac/or generate arg"

Mac OS
sudo ifconfig en1 ether "new_mac_address"
or iwconfig wlan0 wlan "mac"

Windows, i know you can edit the registry and get a more congruently layered mac change through out the system. or you can go into device manager and then right click the network interface and select network address and just type a new one in. though the second way is easier for others to detect depending on what you are doing than with the reg edit method.
