Look up IP spoofing. There maybe software that will spoof it for you in the way you like, otherwise, if you're a programmer, I use Scapy in python, that allows you to forge packets to every detail including the headers.
If you just want to conceal your IP, Tor is free, but needs to be configured properly, otherwise only your traffic going through your browser is proxified. There are a load of proxies out there for all kind of things, but make sure the proxy you get will anonymize you in the particular network protocol you want.
ie, downloading torrents with Tor is not safe
