Pronet 80 Type Numbers

Registration Procedure(s)
IANA does not assign
[Not IETF]
Below is the current list of PRONET 80 Type Numbers.  A protocol
that is on this list does not necessarily mean that there is any
implementation of it on ProNET.

Of these, protocols 1, 14, and 20 are the only ones that have ever
been seen in ARP packets.

For reference, the header is (one byte/line):

        destination hardware address
        source hardware address
        data link header version (2)
        data link header protocol number
        data link header reserved (0)
        data link header reserved (0)

Some protocols have been known to tuck stuff in the reserved fields.

Those who need a protocol number on ProNET-10/80 should contact
Avri Doria <avri&>.
