Explanation
A routing table uses the longest prefix match (most specific subnet mask) to determine the best path and exit interface for forwarding IP packets. ARP table maps IP addresses to MAC addresses, not used for route selection. MAC address table is used by switches to forward frames based on MAC addresses, not IP routes. Netstat table shows active connections and ports, not used for routing decisions. Longest prefix match is a routing principle applied within the routing table.
