ARP - Address Resolution Protocol and
RARP - Reverse Address Resolution Protocol
ARP -
When an Ethernet frame is sent from one host on a LAN to
another, it is the 48-bit Ethernet address that determines
for which interface the frame is destined. The device
driver software never looks at the destination IP address
in the IP datagram.
Address resolution provides a mapping between the two
different forms of addresses: 32-bit IP addresses and
whatever type of address the data link uses.
ARP provides a dynamic mapping from an IP address to the
corresponding hardware address. We use the term dynamic
since it happens automatically and is normally not a
concern of either the application user or the system
administrator.
RARP:
-----
Each system on a network has a unique hardware address,
assigned by the manufacturer of the network interface. The
principle of RARP is for the diskless system to read its
unique hardware address from the interface card and send an
RARP request (a broadcast frame on the network) asking for
someone to reply with the diskless system's IP address (in
an RARP reply).
