Google Public DNS
- boundlessdreamz 17y agoI tested this and it is consistently offering better results than OpenDNS and 4.2.2.2. The results are here http://www.manu-j.com/blog/opendns-alternative-google-dns-rocks/403/ http://www.manu-j.com/blog/opendns-alternative-google-dns-ro... How are the results from inside US ?
- known 17y agoThey are better than 4.2.2.2 in USA.
- eli 17y agoNeat. They even got memorable IP addresses.
- cscotta 17y agoIt's an interesting idea, but based on some early tests it looks like a losing bet to me. My ping from a dedicated 15mb Qwest circuit to 8.8.8.8 and 8.8.4.4 is between 57ms and 75ms. However, cached DNS resolutions run at around 12ms from our default DNS servers. Even uncached resolutions are still way faster than the round-trip to Google. Google Public DNS might be worth it if every single one of your DNS queries would result in a cache miss, but otherwise I don't see the performance improvement Google is gunning for. That said, it is nice to have a public option.

- windsurfer 17y agoThat's funny. I'm with Rogers in Canada, and their DNS requests can take 2000 ms on a normal day.
- jokergd 17y agofunny enough, I get an average of 8ms ping from 8.8.8.8 (9 hops) from my co-lo server quite happy with that
- chrisbolt 17y agoOne of the problems with using 'public' DNS servers like Google and OpenDNS is that content delivery networks return the IPs of their nodes that are closest to your DNS servers based on the assumption that you are on the same network as your DNS servers. I just did a comparison and I am 10ms away from the Akamai node returned by my ISP's DNS servers, 88ms away from the node returned by Google Public DNS, and 20ms away from the node returned by OpenDNS. Even if DNS is faster, it may make everything else slower...
- quellhorst 17y agoGoogle could fix that by setting up relationships with the big CDNs so that they could resolve to the closest locations for you.
- InclinedPlane 17y agoGoogle is one of the biggest CDNs, so maybe they'll start doing that on their own.
- jiaaro 17y agoThat may be true... but I am willing to sacrifice a few hundred ms to avoid the several seconds of frustration when typing 'gmail' into the firefox address bar gets me redirected to some stupid ass ISP specific SERPs page =D
- mechanical_fish 17y agoDo you have any idea how confused I was the first time that happened? An absolutely terrible user experience.
- amalcon 17y agoThe other alternative is to just run your own instance of bind (or dnscache if that's what you prefer). CDN content will usually perform better, but non-CDN content will often lose a few ms because you usually won't have very much in cache. As a bonus, you can perform some stupid LAN tricks.
- lsb 17y agoPhone support! Google Public DNS telephone support 877-590-4367 in the U.S. 770-200-1201 outside the U.S. I wonder if this will be a trend.
- kirubakaran 17y agoJust an automated dude telling you what you already know or can find easily on the web. You can't reach a human at that number, at least for now.
- todd3834 17y agoNow Google can make cash off typo domains by turning it into a Google search and hopefully earning some sponsor link clicks. Not a bad idea. I wonder if they are going to record requested URLs so they know which ones have high traffic to spider more often... I can see a lot of reasons why Google would want to offer this.
- moon_of_moon 17y agoMore like record every URL you visit, and use the content of those websites to determine intent, and then target ads accordingly.
- sgk284 17y agoEh, I don't know if they'll be able to do that too effectively because of NAT and whatnot, but they can certainly use this information in their PageRank calculation. Knowing what pages people visit is an even bigger vote of confidence for the site than seeing how many pages link to it.
- moon_of_moon 17y agoAssume you are logged in or you have a gmail cookie, hell yeah they know.
- inklesspen 17y agoYou're aware that HTTP cookies are not sent to DNS servers, yes?
- moon_of_moon 17y agoYes. I meant if you're not behind a NAT they can correlate your IP with your gmail cookie when you do a search and thereby link a record of the sites you are visiting to your profile to serve you more targeted ads. Apologies for the ambiguity.

- eli 17y agoIn addition to speeding up the internet for everyone, there's a specific benefit to google: http://code.google.com/speed/public-dns/privacy.html http://code.google.com/speed/public-dns/privacy.html They can crunch the data on queries and infer which sites are popular (and in what geographic regions they're popular).
- Subgun 17y agoMore data mining by google under the guise of global awesomeness. The point most people miss is that all of your habits and information are under one roof and only need one subpoena to get your entire electronic life on DVD. This just adds to what they already know about your searching, emailing , communicating and spending.
- conover 17y agoWe don't correlate or combine your information from these logs with any other log data that Google might have about your use of other services, such as data from Web Search and data from advertising on the Google content network. After keeping this data for two weeks, we randomly sample a small subset for permanent storage. It sounds like a good faith effort aimed at speeding things up to me.
- lsb 17y agoJust to be fair, 25% is a small subset, and if all the chrome installations use it as their default DNS, they'd have quite a lot of data.
- kluikens 17y agoI agree, but said data would be a sample from a user base that is far from the general user base of the internet, and Google's user base too. Data from Chrome browsers only would be heavily skewed.
- wgj 17y agoThe Google product manager responded to TechCrunch saying "no blocking, hijacking, or filtering" and responded on privacy with "Collected data includes IP address (up to 48 hours, to detect malicious behavior against the service), ISP information and geographic information (2 weeks each). The data is not correlated with your Google account in any way." http://www.techcrunch.com/2009/12/03/google-dns-opendns/ http://www.techcrunch.com/2009/12/03/google-dns-opendns/

- chrischen 17y agoI always hated the redirection my ISP's DNS and OpenDNS forces. Every time I make a typo, i have to completely retype the URL because they redirect me...
- MoeDrippins 17y agoI've used OpenDNS since they became publicly known and have never gotten a redirect that I can remember. Did I configure that somehow?
