Is possible to change my IP addres? If so how? Is there any legality issue involved in doing that.

Hello Rob,

I have seen a software called Hide my IP which hides IP address.
I have seen it on one of my friends Computer.When I see it first time,IT's just awesome.

It should be noted that it is illegal to hide or alter your ip address in many countries. If you're doing anything that really requires this type of behavior though, you're probably doing something illegal anyway. If you just need to surf anonymously use a proxy server. There are free and paid one's out there.
