Google Launches Public DNS Service
Google has just launched a DNS service similar to OpenDNS, which I’ve written about previously. The service, dubbed “Google Public DNS”, aims to make domain name lookups (i.e. “What does www.google.com mean?”) faster, and is one of the steps in their plan to make the internet faster — or taking control of it, depending on how dramatic you want to sound.
- 8.8.8.8
- 8.8.4.4
For instructions, see the Google Public DNS configuration instructions.
Unlike OpenDNS, which supports itself by providing advertisement-powered search pages for unresolved queries, Google promises that it will never do any form of redirection. A little strange, considering Google runs the largest advertisement service on the planet, but perhaps they genuinely just do want to make the internet faster.
In my tests, Google Public DNS had a significantly faster response time than OpenDNS from my location in Stockholm, Sweden (Europe). If you’d like to find out which DNS servers are right for you, Google also recently released a DNS server benchmark tool called namebench, which tells you just that, factoring in all of the major public DNS services as well as regional ISP DNS servers.
Note that you should never use DNS servers that you don’t trust. DNS providers have full control over what ‘google.com’, ‘gmail.com’, etc. mean to your machine, and can redirect connections to these websites to malicious websites without your knowledge.
