What is the broadcast ARP address?

Explanation:
ARP requests are sent to every device on the local network by using the MAC broadcast address at the data-link layer. This ensures every host hears the request and can respond with its MAC if it owns the requested IP. The MAC broadcast address is FF:FF:FF:FF:FF:FF, meaning all bits are 1. This is why ARP frames destined for all hosts use that address. The other options do not reach all devices at the link layer: an IP broadcast like 255.255.255.255 operates at the IP layer and is not used for ARP’s MAC addressing; a specific MAC or the all-zero MAC would target only particular devices or be unused for broadcast. Therefore, the broadcast ARP address is FF:FF:FF:FF:FF:FF.
