Today Google unveiled its new project: Google Public DNS. It means now anybody can use Google’s DNS managed servers for resolving domain names into IP addresses and back. According to Google it should speedup browsing as well as security. Hope I won’t see adsense ads once tried to load expired domain name (that’s how OpenDNS acts today).

Here are easy-to-remember Google Public DNS IP addresses: 8.8.8.8 and 8.8.4.4.

In order to set up Google public DNS to your Linux settings place the following lines into /etc/resolv.conf:

nameserver 8.8.8.8
nameserver 8.8.4.4

Use command dig @8.8.8.8 linuxscrew.com to test how long it takes to resolve linuxscrew.com:

artiomix@artiomix-laptop:~$ dig @8.8.8.8 linuxscrew.com
...
;; ANSWER SECTION:
linuxscrew.com. 51844 IN A 69.164.195.222

    I googled open DNS vs. Google Puble DNS and found this story or blog titled "Google turns the page... in a bad way." I think is worth reading.

    Great post!

    I would like to thank you for sharing your thoughts. You are putting very good effort into the stuff you post.

    The Domain Name System (DNS) is a hierarchical naming system for computers, services, or any resource connected to the Internet or a private network.

    4.2.2.2 and 4.2.2.1 is still faster. and besides 8.8.8.8 is owned by level 3, not google.

    I know that there is more to responce than just latency but pinging 8.8.8.8 averages 19/20 ms, 4.2.2.2 is nearer 80.

    Obviously I like your web site, however you have to check the spelling on quite a few of your posts. Several of them are rife with spelling issues and I find it very troublesome to tell you. On the other hand I will surely come back again!

    Hi there! I know this is somewhat off topic but I was wondering
    which blog platform are you using for this site? I'm getting sick and tired of Wordpress because I've had
    issues with hackers and I'm looking at options for another platform. I would be fantastic if you could point me in the direction of a good platform.

    I constantly spent my half an hour to read this blog's articles or reviews everyday along with a mug of coffee.
