Usually it is, but for a while keying it to a "host name" was
popular.  This actually makes some sense, since it ties it to a name
rather than a specific machine, but of course the way Microsoft
implemented it involved abusing a parameter meant for another purpose.

I'd only spoof it as a last resort, though.  Why tell a lie when the truth
will suffice?  And why risk having problems later if you happen to connect
both machines to the same Ethernet?

You don't need a special program.  Just run winipcfg.
