The protocol that translates Internet Protocol, or IP, addresses into physical network addresses One of the many members of the TCP/IP protocol suite, ARP is a key player in the process that allows a packet of data addressed to a particular Internet host to find its destination See also DNS, RARP, and TCP/IP
(Address Resolution Protocol) - A TCP/IP protocol used to obtain a node's physical address when only its logical IP address is known An ARP request with the IP address is broadcast onto the network, and the node with that address responds by sending back its hardware address so that packets can be transmitted The protocol translates IP addresses into physical network addresses, such as Ethernet IDs, by converting the 32-bit IP addresses into the 48-bit physical network Ethernet addresses Another TCP/IP protocol which plays a less visible, but equally important role in the operation of TCP/IP networks Reverse ARP, or RARP, is used by a diskless workstation to obtain its logical IP address
Address Resolution Protocol A TCP/IP protocol used for resolving local network addresses by mapping a physical address (i e a MAC address) to an IP address
Address Resolution Protocol, arp RFC826 A low-level protocol which, given an IP address on the local network, returns the Ethernet MAC address of the corresponding interface cf RARP
Address Resolution Protocol The Internet protocol used to dynamically map Internet addresses to physical (hardware) addresses on local area networks Limited to networks that support hardware broadcast
Address Resolution Protocol, arp See RFC826 A low-level protocol which, given an IP address on the local network, returns the Ethernet MAC address of the corresponding interface cf RARP
Address Resolution Protocol Used to dynamically discover the low-level physical network hardware address that corresponds to the high level IP Address for a given host, for instance ARP is limited to physical network systems that support broadcast packets that can be heard by all hosts on the network See also Proxy ARP
(n ) Address resolution protocol under TCP/IP used to dynamically bind a high level IP address to a low-level physical hardware address ARP is limited to a single physical network that supports hardware broadcasting
Address Resolution Protocol A network protocol that allows hosts to discover a node's hardware address from its IP address ARP requests are generally sent as broadcast to all nodes, and the node whose IP address matches that in the request replies The arp command on UNIX hosts shows the current IP address to hardware address mapping; the arp command on the Server shows the current IP host table
Address Resolution Protocol A dynamic method of discovering the MAC address of a device on the network A device sends an ARP request out with the IP address of the machine it is looking for The machine with that IP address answers, sending its MAC address to the requester
Acronym for Address Resolution Protocol, a protocol for translating between IP addresses and MAC-layer addresses in an ethernet Defined in RFC 826 See Also: BOOTP, DHCP, and RARP
