To deliver an arriving packet to a destination host on a subnet connected to a router, the router needs to know the destination host's IP address to route the packet to the correct subnet. Additionally, the router needs to know the destination host's data link layer address (such as MAC address) to forward the packet to the correct host on the subnet. Therefore, both the IP address and data link layer address are required for the router to deliver the packet to the destination host on a subnet.
