The following is extracted from rfc1010: ADDRESS RESOLUTION PROTOCOL PARAMETERS The Address Resolution Protocol (ARP) specified in RFC 826 [64] has several parameters. The assigned values for these parameters are listed here. Assignments: Operation Code (op) 1 REQUEST 2 REPLY Hardware Type (hrd) Type Description References ---- ----------- ---------- 1 Ethernet (10Mb) [JBP] 2 Experimental Ethernet (3Mb) [JBP] 3 Amateur Radio AX.25 [PXK] 4 Proteon ProNET Token Ring [JBP] 5 Chaos [GXP] 6 IEEE 802 Networks [JBP] 7 ARCNET [JBP] Protocol Type (pro) Use the same codes as listed in the section called "Ethernet Numbers of Interest" (all hardware types use this code set for the protocol type). -- Michael A.
