Actually, it's just phase IV. Phase III didn't have ethernet support

It changes the MAC address if it's also in the Phase IV domain, otherwise
it don't.

But Phase V isn't that interesting to have, since we're only talking VMS
then. And those machines might as well play tcp/ip as well.
Phase IV means a lot of other DEC machines, so that would be nice.
(Linux have DECnet phase IV, but it's so lousy it's unusable.)
