So I have several USB modems and several computers. Dumb question #1 I'm wondering which combo of modem's & computers I will need to use to have a different IP address. Eg Same computer with different modems? Or same modem with the different computers? I guess the question is - is my IP address linked to my computer, or my modem? Not doing anything sinister, don't really need to cloak myself but there's some accounts that I don't want to be linked together. The stuff that's not "wrong"...but it would void your warranty. Dumb question #2 I created webstes, gmail, Facebook accounts etc with my old computer before if crashed & burned, I'm still using the same sim card in a different USB stick modem. So the IP address that Google credits to creating that Gmail account...is that different from the IP address I'm using right now? I seriously don't know how I made it this far without knowing this stuff!! Thanks for your time guys.
