The parsing process of ARP

Address Resolution Protocol, which is ARP (Resolution Protocol), is based on IP address gets The physical address of a TCP/IP protocol . when the host sends the message, the ARP request containing the destination IP address is broadcast to all hosts on the network, and the return message is received to determine the physical address of the target, and when the return message is received, the IP address and physical address are stored in the native ARP cache and retained for a certain amount of time. Query the ARP cache directly on the next request to conserve resources.

parsing Process :

ARP is used to resolve a known IP address to a MAC address for communication on the MAC layer. In order to determine the target

MAC address, first look for the ARP cache table. If the MAC address you are looking for is not in the table, ARP sends a broadcast

To discover the destination's MAC address and log it to the ARP cache table for the next lookup.
