ARP Parameters



ADDRESS RESOLUTION PROTOCOL PARAMETERS

The Address Resolution Protocol (ARP) specified in [RFC826] has
several parameters.  The assigned values for these parameters are
listed here.

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, contact: David Brownell
(suneast!helium!db@Sun.COM).

INVERSE ADDRESS RESOULUTION PROTOCOL

The Inverse Address Resolution Protocol (IARP) specified in [RFC1293]
uses the "InARP" codes below.

Assignments:
