Address Resolution Protocol (ARP) is a protocol for mapping an Internet Protocol address to a physical machine address that is recognized in the local network. A table, usually called the ARP cache, i [..]

The protocol by which layer-3 IP addresses are resolved into layer-2 link local addresses.

A Transmission Control Protocol/Internet Protocol (TCP/IP) protocol that dynamically binds a Network-Layer IP address to a Data-Link-Layer physical hardware address, e.g., Ethernet address.

Internetworking Dictionary Used to dynamically discover the low level physical network hardware address that corresponds to the high level IP address for a given host. ARP is limited to physical network systems that support broadcast packets that can be heard by all hosts on the network. It is defined in RFC 826. See also: proxy ARP.

A method for finding a host's Ethernet address from its Internet address. It works like this: The sender broadcasts an ARP packet containing the Internet address of another host and waits for it [..]

A network-layer protocol used in TCP/IP transmission. ARP is used by end stations to determine the physical address of other stations on the same LAN.

The Address Resolution Protocol (ARP) is a method for finding a host's Ethernet address from its IP address. This is usually applicable in computer networking using the internet protocol suite. T [..]

ARP is the protocol that traces IP addresses to MAC addresses - see also Reverse Address Resolution Protocol (RAPP).

A low-level computer networking protocol used for resolution of a Network Layer address (IP) into a Data Link Layer address (Ethernet MAC address).

Address Resolution Protocol (ARP) is a low-level network protocol for translating network layer addresses into link layer addresses. ARP lies between layers 2 and 3 of the OSI model, although ARP was [..]

<networking, protocol> (ARP) A method for finding a host's Ethernet address from its Internet address. The sender broadcasts an ARP packet containing the Internet address of another host and waits for it (or some other host) to send back its Ethernet address. Each host maintains a cache of address translations to reduce delay and loading [..]

Address Resolution Protocol. ARP is the protocol used by IP (as in TCP/IP) for address resolution. Address resolution refers to the ability of a station to resolve another station's MAC (hardware) address given its IP address.

(computing,Internet) The protocol used to translate IP numbers into MAC addresses to support communication on a LAN.
