Can anyone please help me out

Can anyone tell me how to do IP spoofing?

I just need that to post in a Discussion board (not this one ;) with a different IP.

Do you know any software out there which I can download, install and use right away to change my ip?

Why would you need to spoof your IP? Sounds like something shady to me. Were you banned and you are trying to get back in?
