Which destination address is used in an ARP request frame?
In an ARP (Address Resolution Protocol) request frame, the destination address used is the broadcast address, which is a special address that allows a frame to be received by all devices on the local network.
The broadcast address is typically represented as a series of all 1s (e.g., 255.255.255.255 in IPv4 or ff:ff:ff:ff:ff:ff in IPv6).
The reason why the broadcast address is used as the destination address in an ARP request is that the purpose of an ARP request is to determine the MAC address (Ethernet address) of a given IP address.
Since the MAC address is required for the frame to reach the intended recipient, the request is sent to all devices on the network, hoping that the device with the corresponding IP address will respond with its MAC address.
