Google has launched a free public domain name service, which can serve as an alternative to the service typically provided by ISPs. Google insists it will respect its customers' privacy and not bombard them with ads.  (Source: SEO For Blogging)
Service raises competitive, privacy concerns

Google dominates everything from web search to online applications.  However, a new product may be one of its most important yet --  Google has launched a public Domain Name Service.

A Domain Name Service, commonly referred to as a DNS, acts like an internet switchboard, converting a text address string like "www.dailytech.com" into an IP address -- a series of dot-separated number fields that tell the computer exactly where to send its request for information to.  Most internet service providers provide their own DNS, but you do have the chance to use a third-party service.

Now Google has become the biggest party yet to jump on this chance, launching Google Public DNS.  To try the service out, refer to instructions on Google's Code Blog, available here.

The DNS allows Google to control the routing of internet traffic, and see much of the user information typically held only by ISPs.  Google insists, though, that it's working hard to keep its users info private and anonymous.  It says that it will only save user IPs for 24 to 48 hours, and that's only to protect against attacks or identify technical problems.  It will store your "metro-level" (probably city and state) location and the pages you visit -- but it says that info isn't associated with any information that can identify you (like IP logs).

Google also logs many technical details about your requests, including how long they took.  According to Google, that's the upside of its new service -- it can "make users' web-surfing experiences faster, safer and more reliable."

Surprisingly, unlike some ISPs that place ads on the error page when a domain can't be resolved, Google's service is ad free for now.  It states, "If you issue a query for a domain name that does not exist, Google Public DNS always returns an NXDOMAIN record, as per the DNS protocol standards."

However, not all are convinced that Google's service will stay ad-free for long.  Describes OpenDNS's David Ulevitch, "You have to remember they are also the largest advertising and redirection company on the Internet.  To think that Google's DNS service is for the benefit of the Internet would be naive. They know there is value in controlling more of your Internet experience, and I would expect them to explore that fully."

Dunno about resolve times (hard to test easily for me), but fwiw ping times to the Google DNS server is noticably slower than to my regular DNS server.

That's probably because your ISP's DNS is a few hops closer to you than Google's, and Google's DNS is probably behind a firewall. Your ISP might not have a firewall between you and the server, even if there is one between it and the 'net.

You can measure the performance of any traffic using tcpdump or Wireshark by comparing the outbound and inbound timestamps.

Actually the DNS I use isn't that of my ISP (Verizon, FiOS specifically), I use a third party "outside of Verizon" one -- and is the one I compared Google with.

Obviously.

I tried 5 different speed tests around the US under each of the OpenDNS, my ISP (Cox) DNS and Google DNS, Google's was significantly slower, on average 2-4Mbps slower, and for a 12Mbps connection that is a good chuck. My ISP DNS was just a shade slower (by 200-500Kbps) than OpenDNS.

I will stick with the DNS company that has handled the DNS requests for many many years now, and not an advertising company.

A speed test using different DNS servers is basically meaningless. DNS is only used when the name is first entered - your computer caches the information so it doesn't have to look it up again.

Having a slow DNS server will not show up as a slow connection, it would show up as a short pause first making the connection.

I don't know about Vista/7, but in XP they get whiped after reboot.. You can also whipe them manually (which is what I did to test) 'ipconfig /flushdns' in command prompt to wipe them.

It is a slower, I've also tested it myself. Takes slightly longer to resolve the address, although there is no reason to be surprised about this...

Doing this in 7/Vista you need to run the console as administrator..

Even if you don't use their service.

I don't mind using their search engine. But I don't want them knowing what sites I directly type into the address bar as well. That is one step too much.

You should never place all your eggs in one basket. Seems reasonable advice to me.

He has a legitimate point. Google already has incredible amounts of user inormation, but if you use, say, Bing or just go into a URL directly they can't use that to adjust their advertising targeting to more accurately fit you.

Now they can.


Reasons to use a pub DNS
By GaryJohnson on 12/4/2009 12:27:41 PM , Rating: 3
A) your ISP doesn't have a DNS
B) your ISP's DNS is god awful slow
C) your ISP hosts ads on their DNS
Any others?

Where's the Google Public Proxy? They've stopped people from using translator for this:

Most of the time its B:
and even still - most isp dns servers are mediocre. I have been using opendns for years because it is just simply overall a faster server making the net just a tad more responsive.
They probably do the same thing, so I would be interested to see and might try Google's (currently) ad free offering.

The government has tried to create a pervasive system to spy on it's citizens, using all types of various means, and reasons, from security threats, to protecting the children.
Google has managed to do it within a few short years, and without stealing from the taxpayer!
Of course the whole GUID that google now uses, will never be tied to your DNS requests, and if they 'accidentally' do you can always install another tracking cookie that tracks that you have 'opted-out'.
Of course the gov. will now 'politely' mandate that google keep it's logs for years and share them with any agency at anytime for any reason. It's all to keep us safe though, don't you worry ;p

I won't worry till it becomes illegal to voice your opinion of the government.


Quite Good
By Trisagion on 12/6/2009 1:17:13 PM , Rating: 2
I've been using this for a few days and it's quite good. It has easy to remember IPs (8.8.8.8 and 8.8.4.4, so it's also good for testing, in addition to the well known 4.2.2.x range). The DNS is reasonably fast and if a record is not found, the browser correctly returns an error instead of being redirected to a stupid error page.

I used to use DNS Advantage before, which is also good, but has those customized 'Not Found' pages.

The worst of the lot is OpenDNS, which in addition to having error pages has filters. I think it allows filters based on range or something, since even though I have an account, every now and then I find common sites like Hotmail and the like blocked for my IP. Go figure.

I don't think people using public DNS servers should be worried about Google's privacy since the policy is mostly the same for all of them anyway.




awefully limited target
By kattanna on 12/7/2009 11:48:49 AM , Rating: 2
seems this new service has a very limited target audience, as most people are not going to bother changing their DNS settings, even if they do know how.

so i have to wonder, whats the point?
