Address Resolution Protocol (ARP)

The Address Resolution Protocol (ARP) is a TCP/IP protocol that is used to obtain a network node's physical address. ARP operates at layers 2 (Data Link) and 3 (Network) of the Open Systems Interconnection (OSI) model. The physical address, also referred to as the Machine Access Control (MAC) address, is the unique serial number that identifies one network card from another.

The network maintains a list of devices, IP addresses, and physical addresses in the ARP cache. With the NETWORK KM, you can view the ARP cache and add or delete resources (computers, printers, routers, anything with a network card) from it.

The NETWORK tasks related to Address Resolution Protocol (ARP) are described in detail on the following pages:
