It may be helpful to think of ARP as working with "hardware" addresses in
whatever form is appropriate to the medium. On Ethernet, ARP queries are sent
to the Ethernet broadcast address, "FF:FF:FF:FF:FF:FF." On AX.25, ARP queries
are sent to the AX.25 broadcast address, "QST-0." These are functionally
equivalent, but are different because the medium in each case is different.
