TCP/IP Address Resolution Protocol (ARP)

ARP is a full-featured, dynamic resolution protocol used to match IP addresses to underlying data link layer addresses. Originally developed for Ethernet, it has now been generalized to allow IP to operate over a wide variety of layer 2 technologies.

Note

The Address Resolution Protocol described here is used for resolving unicast addresses in version 4 of the Internet Protocol (IPv4). Multicast addresses under IPv4 use a direct mapping method, and IPv6 uses the new Neighbor Discovery (ND) Protocol instead of ARP. These methods are both discussed near the end of this chapter.

Tip
