Address Resolution Protocol (ARP) Parameters (last updated 2006-08-08) Registries included below: - Operation Codes - Hardware Types - Protocol Types Note: Reverse Address Resolution Protocol Operation Codes The Reverse Address Resolution Protocol (RARP) specified in [RFC903] uses the "Reverse" codes below. DYNAMIC REVERSE ARP The Dynamic Reverse Address Resolution Protocol (DRARP) uses the "DRARP" codes below. For further information, see [RFC1931] INVERSE ADDRESS RESOLUTION PROTOCOL The Inverse Address Resolution Protocol (IARP) specified in [RFC1293] uses the "InARP" codes below.
