heres an example.. if you look at my "IP Address Logged"
it says that I live in hongkong... previusly it was in Canada... I can randomly change that to Japan or where ever it wants or I can manulay select a country and it will randomy pick an ISP from that country.
Though it doesnt change our MAC Address.... you can do that with another software if a forum such as this one desides to ban o using yor mac address. It can also ban your hard ware adress such as your hard drive... but thats why you should alwase spoof your Hardware Address even if your playing game that everyone cheats on (Americas Army, Counter Strike)
