ARP protocol:

Use the ARP protocol to communicate with the MAC address:        the communication between IP depends on the MAC address, the IP address indicates the address that the node is assigned to, the MAC address refers to the fixed address that the network card belongs to, and the IP address can match with the MAC address. The IP address can be transformed, but the MAC address will not change at all.    usually the two sides of the communication are not on the same LAN, but through multiple computers and network devices. When transiting, use the MAC address of the next relay device to search for the next transit target. In this case, the ARP protocol (Adress Resolution Protocol Address Resolution Protocol) can be used to detect the corresponding MAC address based on the IP address of the communication party.
