Google Public DNS Servers Launched

In virtually all cases, people’s ISP DNS servers will be faster.

I’m wondering what exactly google’s motive is behind their launch of this service.

Fun enough, Google’s public resolvers won’t give you an IPv6 address for http://www.google.com:

$ dig aaaa http://www.l.google.com @8.8.8.8 +short
$

You have to go to other parties to find that:

$ dig aaaa http://www.l.google.com @2001:470:20::2 +short
2a00:1450:8005::69
2a00:1450:8005::63
2a00:1450:8005::68
2a00:1450:8005::93
2a00:1450:8005::6a
2a00:1450:8005::67
$

I know that one, but that’s not what I’m looking for. I want to be able to look up the AAAA record for http://www.google.com (CNAME http://www.l.google.com) directly, and I cannot do that at Google’s public resolvers. I.e., what I want is the second scenario on the pic at http://www.google.com/intl/en/ipv6/ — and I can do just that by using 2001:470:20::2 as resolver…

The reason for which Google gives you this service nice and clean even if it is a lot slower than more than 99% of ISP (even basic) DNS servers is quite clear for me:
DNS queries are very useful in building a very specific and accurate profile of a someone’s behavior on Internet; and this is extremely useful in all kinds of optimization for search engines (SEO) and Company and also is a very normal, obvious step to globalization (as in global control)…
All they have to do is convince you to use them; and it would not be very hard as many people consider Google services quite stable and “great” without thinking to what they give up in using them.
Corroborate this with other actions Google has taken in last years and you may see that even having Google as ISP anywhere in the world won’t be very hard to believe…. imagine only what can be obtained from analyzing all traffic a person / organization does! (this kind of analysis is already used for years in planing targeted hacking attacks for example)

I enabled open DNS after experiencing problems with my home internet connection, after upgrading to Ubuntu 9.10. It definitely improved things. I block the advertisements using adsweep etc via greasemonkey. The reason this article caught my attention are the comments by Vivek Gite. I started learning shell scripting because of his excellent tutorial. Thank you Vivek! I will not be using Googles DNS services yet till they have gone through the teething problems that all new things are prone to. Thanks once again Vivek!

i was wondering that ISP’s can configure their routers to direct DNS requests to their own servers.

Hi Vivek,
will this break the CDN setup?
ie. give you the caching servers closer to google dns?
or will it just do the resolving from a DNS server closer to Google, and still give you the cache servers closer to you?

thanks,
Yonit

ps. – why did you take off the url part from your comments?

Pertamaaax .. Gan!!!,

I will try …thanks for research opendns, I hope more smootly than ISP on my country yg agak lemot gitu loh <> :P

Does Google provide Phishing Protection, Filters, etc. like that of OpenDNS ?

@Aaqil,

Are you a geeky desktop user? If so learn how to setup your own squid and SquidGuard blocking service.

OpenDNS has its own problem just like Google DNS server. Both of them sell your personal data and they do not have clear cut privacy policy.

This great man

The IP address is very easy to remember.
I think it’s the only advantage of this public DNS service.
My ISP DNS (Telefonica) is currently working faster.

Cheers!
