In the absence of a Designated Router, DECnet endnodes (on an Ethernet)
will attempt to communicate by sending to the destination node's Ethernet
address.  This Ethernet address is computed from the node's DECnet host
number.  This is why all DECnet hosts on an Ethernet have funny addresses.

A DECnet Ethernet address looks like AA-00-04-00-XX-YY, where XX-YY is the
DECnet host number with the bytes swapped (don't shoot me, I'm just the
piano player).
