Furthermore, whether the RFC [1918] says so or not, I'm going to block these packets at *my* border routers, because:
Curious as to the cost (added latency) in doing RFC 1918 source address filtering on all packets in the context of cost-benfit analysis.
on a router that's not doing filtering, it's going to be a small hit. i'm going to infer, however, that any router that's not doing filtering is probably not doing much traffic. and any router that is doing a lot of traffic, is already doing filtering. so it's less of a hit. -- |-----< "CODE WARRIOR" >-----| codewarrior@daemon.org * "ah! i see you have the internet twofsonet@graffiti.com (Andrew Brown) that goes *ping*!" andrew@crossbar.com * "information is power -- share the wealth."
