What kind of address is the destination MAC address in an RARP request?

In a Reverse Address Resolution Protocol (RARP) request, the destination MAC address is typically set to the broadcast address (FF:FF:FF:FF:FF:FF). This allows the RARP request to be sent to all devices on the local network segment, ensuring that the RARP server, which is responsible for resolving the MAC address to an IP address, can receive the request from any client that needs to determine its IP address.
