On a small network, the caching function wouldn't provide much advantage.
I disagree, but I haven't really used wireshark to verify it in a couple years. To the best of my knowledge, if a website has 20 images on it referenced by hostname, then the browser will do a DNS lookup for each of those 20. If you're not running a caching DNS server either on that box itself or on your lan somewhere, then those 20 queries have to go out to the DNS server you're using. At normal ISP speeds, that can add up. As to using the DNS server in the router, I've always assumed all it did was forward your requests to the ISP for you. Do low end home routers actually cache DNS queries? Greg -- Greg Freemyer -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
