About the App
Address Resolution Protocol (ARP) Tables. The Address Resolution Protocol (ARP), as you might guess, is designed for resolving addresses. To tie together the data link (Layer 2) layer and the network (Layer 3) layer, a mechanism must exist that maps data-link layer addressing to network layer addressing; this mechanism is ARP. RP stands for Address Resolution Protocol. ARP is a protocol by which we find out the layer 2 address (link layer address or MAC address) associated with the IP address. Before we talk more. This is called 'ARP Cache Validation' packet means ARP timeout has expired and switch wants to try the validation the same 'is this ARP validate with the same IP'. I think, we must distinguosh between the target MAC address of the frame (where the frame is sent to) and the target MAC address within the payload of the ARP packet. Type 'arp -a' in the command prompt. This lists a number of MAC addresses with the associated IP addresses. Since you have the MAC address, scroll down the list to find the associated IP address.
