Lines: 7 The Arp cache in BSD (at least 4.2) is aged, but not quite the way you need if you're going to be changing things around a lot. Entries stay in the cache as long as they're being used. So if you have some process retrying a connection to a given address with a retry time less than the cache timeout, it will never time out, even if the entry no longer points anywhere useful. Entries should time out eventually whether they're being used or not.
