pcmag.com — Google touts its new, free, Public DNS service as a speedier, safer version to access the Web. There's some truth to Google's claims, and its speed advantage may be compounded when a site your browser loads has to access several different URLs to load all of its content.

"Google doesn't filter phishing sites and block the domains of known malware-distributing sites." Too bad their search doesn't do that. Half the sites in Korea show up in google search as having "malware". None of them do, but it is because they are so reliant on activex that google often mislabels the most innocuous site. Then they wonder why they have such a tiny market share here. It is because Koreans don't have to have to copy and paste every time they search for something.

OpenDNS is based on hijacking traffic and injecting ads. It actually breaks DNS services if you have subdomains and rely on that to find hosts... NEVER use OpenDNS.

Their Privacy Policy is to throw out all IP's every 24 hours, and not use any data gathered with other services (Gmail, etc)

You can configure unlimited extra DNS IPs under TCP/IP->advanced. Then they'll already be ready if your ISP's DNS servers go down, and you don't have to remember or do anything later. If you have a router, it depends on it's capabilities, and if you are using bind on a gateway server, just add any number of ips to the "forwarders" section of the appropriate config file (likely /etc/bind/named.conf.options).You'll still get spam results if /any/ listed DNS server hijacks non-existing domains, though.

You can't just query a popular domain over and over again to get a meaningful comparison. Queries get cached. The real question is which server does a better job of maintaining an efficient cache and/or most efficiently handles cache misses.Google renews records before they expire and claims to keep cache more relevant by preferring to stuff it with popular domain queries before the most recent queries. These details should make a slight improvement in real-world browsing, though if you're using a caching router or gateway (pretty common these days), that potential for improvement is *very* small since your local cache is the fastest /and/ most relevant already, once seeded. When they release their optimizations and they make their way into your local-network DNS caching server, then you should see the most improvement, though still small.

Performance is not Google's primary focus with this endeavor, though. They are more interested in improving accuracy and security with the current DNS protocol while we wait for DNSSEC.

@dhughes: I have the same setup, but I'm growing tired of OpenDNS. I don't like how typing in a keyword yields results instead of going straight to the first site.
