information in its ARP cache. Newer information always replaces existing content in the ARP 
cache.

The number of supported ARP entries is platform-dependent.

Devices can be moved in a network, which means the IP address that was at one time 
associated with a certain MAC address is now found using a different MAC, or may have 
disappeared from the network altogether (i.e., it has been reconfigured, disconnected, or 
powered off). This leads to stale information in the ARP cache unless entries are updated in 
reaction to new information seen on the network, periodically refreshed to determine if an 
address still exists, or removed from the cache if the entry has not been identified as a sender 
of an ARP packet during the course of an ageout interval, usually specified via configuration.
