Re: TCP session disconnection caused by Code Red?
RFC 1122 mandates that you query for a particular ARP destination no more frequently than once per second. RFC 1122 also notes a number of reasons why people may want to make the positive ARP cache timeout long -- if one suppresses ARP queries for that time, you'll have the situation where if a popular host goes down for a period of time, it is effectively off the network for a long period while waiting for ARP negative caches to timeout. Probably a bad idea. Rate limiting, as RFC 1122 suggests, would seem to be much better. Craig
