Everything is possible of course. You should have some basic knowledgde of the TCP protocol (assuming you are using this). When you (A) are sending data to another computer (B), then B doesn't know that A was sending this data. That's why A sends his IP with this data. What you will have to do is replace this IP by another (this process is called spoofing btw). The other computer won't know that you were sending this data.

This always works BUT it has one big disadvantage. Computer B sees the IP in your data and when it wants to answer it sends the data to that IP (which isn't yours :P) and you will not receive it. 2 way communication is not possible while spoofing, for that you need some other tricks. But if you only want to send data and the other one must not see your true IP then spoofing will do the trick.

There are some more things to deal with. If the fake IP is not online at that moment then B will receive an error which says that the destination is not found and will terminate the TCP connection. If a computer (C) is online with that IP and A sends a TCP request to B (with the IP of C) then B will answer to C that he accepts the TCP connection. But C doens't know at all about a request for a connection with B and will tell him that. B will cancel the connection in that case. What you should do is have an online IP which is not able to send data. You could DoS attack it but that is highly illegal and I'm not advertising for this because altough I find cracking highly interesting, you'll never see me doing it. Maybe your wishes aren't illegal but I think you willhave to do illegal things to fullfil them. So advice, don't do it ;)
