Hack on other pc in same house

Hey guys, i want to hack on my laptop but i dont want to get traced on my main pc..
Is there a way to change my IP for this laptop, as if i play from another place?
Thanks for help!

And how i use that?
Can i switch back to my old IP?

Yu no know google?

I used google, i want a good vpn.. Is there one you can suggest (maybe free)?

Or can i even get a ban (on desktop pc) when i play with hacks on the laptop?
I mean, yes i am im the same network with my other pc but i dont have hacks on my desktop pc..
Does anyone know this?

kepard is a good VPN.. not exactly free though :/
