The best way is to consult the local arp table. If the entry has expired then ping the host and (if it is alive) your arp table will updated. Another way would be to run something like arpwatch. Either way it makes sense to have arp entries expire. Consider a situation where DHCP is used on the LAN. The IP addresses change which hosts they are associated with and therefore a IP addr may have different MAC address at any given point in time.
