I can verify that this is normal behaviour for Suns when running SunOS 4
and configured with multiple Ethernet interfaces: every one gets the
same address. I presume it's a feature of the PROM. It would only be a
problem if you connected >1 interfaces to the same Ethernet segment,
which would be a pretty weird thing to do.
