    Gogole Public DNS Google Public DNS LaunchedThose, who are into Networking, must be aware of a fast DNS for faster loading of web pages. Many time, you may be getting errors like web-site failed to load, or internet failed despite of you connected to Internet. One such, issue I have seen at my friend place, where his default Airtel DNS, failed to load Facebook on his system. One way to get rid of such issue is by using Public DNS like OpenDNS and now Google Public DNS.

    Yes, Google has launched a public DNS to speed up Internet. This new, Google DNS can be used by any individual and like Open DNS, it’s free to use without any catch.

    You might need Open DNS or new DNS released by Google to make sure you see the name server changes instantly , Security, Less page not found errors. Usually when you get an Internet connection, your ISP offer you its own DNS which takes time to refresh.

    A Faster DNS will make sure that while performing a website lookup, it takes the smallest roundtrip and page will load faster. Another reason to use a secure and reliable DNS system, is to avoid DNS spoofing. I used to use Open DNS earlier but after Google released its own DNS system I feel it may be better.

    I just pinged both the DNS system (Google DNS and Open DNS ) Here are the results

    I can clearly see the latency difference here. This made my choice clear.

    Now something from Official Google announcement

    Most of us aren’t familiar with DNS because it’s often handled automatically by our Internet Service Provider (ISP), but it provides an essential function for the web. You could think of it as the switchboard of the Internet, converting easy-to-remember domain names — e.g.,www.google.com — into the unique Internet Protocol (IP) numbers — e.g., 74.125.45.100 — that computers use to communicate with one another.

    You can get Google DNS from official Google DNS page

    For now it is

    • 8.8.8.8
    • 8.8.4.4

    For IPV6, use following settings:

    2001:4860:4860::8888 and 2001:4860:4860::8844

    Have you ever tried seeing the difference after changing DNS ? Share your thoughts. Here is a guide, on how to change DNS to Google DNS. Do let me know, if you have more query about Google Public DNS. You can also use DNS benchmark to check which DNS will be fastest for your ISP.

    According to 2012 report from Google, almost 70 billion request is being served by Google DNS every day.

    No it will be.. Last night I made a name server change to one of my client and it name server replication was not showing in Google DNS but when I changed it to OPEN DNS I can see the name server change.

    One more good service from google. But as they more secured, hope not to get site censored. We love to browse each and every site.

    Well, you are right. Even for me, the Google DNS server has lower latency. However, when I ran performance tests (as you know) for random domain resolution queries, the performance of the two came out comparable.

    This means that OpenDNS is probably much faster at resolving queries, compared to GoogleDNS. What do you think?
