The Ethernet address is large because it is assigned to a device
permanently, and remains the same even if the device is moved to another
network. Also, the Ethernet address is the same size, and is identical to,
the "host" portion of the XNS address used by a higher-level protocol known
as IDP (Internet Datagram Protocol - the XNS counterpart of IP). Since
these addresses are the same, there is no need for an ARP protocol in XNS.
