ARP timeout refers to the duration for which an Address Resolution Protocol (ARP) cache entry remains valid before it is removed or refreshed. When a device communicates over a network, it uses ARP to map IP addresses to MAC addresses, storing this information in a cache to optimize future communications. If the entry is not used within the specified timeout period, it is cleared to ensure the cache remains current, preventing potential communication issues due to outdated information. The default timeout can vary by operating system and configuration.
