Q

Can I change the amount of time addresses stay in the ARP cache?

Thanks for the info on ArpCacheSize -- is there an entry such as "ArpCacheTimeout" to change the time the addresses stay in the cache? I teach and would like to increase the amount of time the entries are held in the cache to allow better demonstrations, lab projects, etc., concerning ARP.
Try the REG_DWORD value ArpCacheLife in HKLM\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters. Set the value to the number of seconds you want each entry to live. 10 minutes is 600 seconds, for example.
