The route table is fundamental for networkable devices as it stores routing information necessary for packet forwarding. Each entry in a route table includes details about the destination network and the next hop, which helps determine the best path for data to travel toward its destination. When a packet arrives at the device, it checks the route table to find the most appropriate outgoing interface for forwarding the packet based on its destination IP address.

The other options highlight functions that are not specifically related to the route table's purpose. Connecting to the internet involves a broader set of protocols and configurations that incorporate more than just routing information. Maintaining a list of MAC addresses pertains to the function of a MAC address table, often used in switches, which is separate from the IP-based routing function. Processing ARP (Address Resolution Protocol) requests is related to resolving IP addresses to MAC addresses, which again is a different operational layer and not a direct function of the route table.
