hey - i've found a nice arp setting : net.ipv4.neigh.eth0.base_reachable_time

from man 7 arp :

" Once  a  neighbor  has  been  found,  the  entry  is  considered  to
 be valid for at least a random value (...)  Defaults to 30 seconds."

My next questions :

- can I adjust it to be "0" - will it mean "infinite" ?

- why there's so short default time of re-sending the arp cache
refresh for and ip address ?
