[DNS] Comcast slow/Timeout DNS lookup
I have the blast (50mb/s) and can see this throughput when downloading from newsgroups. But, my web browsing seems very slow.
I suspected DNS response time and I'm fairly certain that's the problem. Using ns_bench »SBC DSL FAQ »How do I test DNS lookup latency with ns_bench? to determine the response times from the comcast and OpenDNS servers, I consistently see timeouts with the comcast servers:
C:\temp\ns_bench\win32>ns_bench 18.104.22.168 22.214.171.124 126.96.36.199 188.8.131.52Does this sound reasonable? When I change the DNS entries on computer to those of OpenDNS, it seems faster...
