How long must my Internet be unplugged to change my IP?

Question

I heard it was 8 hours...

Or is there a simpler way to do it?

(Windows Vista, by the way)

Answer 1

A minute or 2.  What kind of computer you have makes no difference.

Make sure you turn off (Unplug?) the ISP MODEM not your router or you won't have done anything.

If you also have a router, I usually turn that off also and turn it back on a minute after I turn the modem on.
