Lightbulb Google launches public DNS. Edit: See pg2 for choosing the best DNS servers for you

Anyone tried this yet? Google Public DNS

I will set this up on my home n/w and post feedback here.

Ouch - for those Google-haters, another chance to take potshots at it. Privacy and other ethical issues are bound to be brought up.

Service will work, but how is it going to utilize private data? How much access Google gets to the innards of a system, is not spelled out clearly. Initially they might only harvest browsing patterns and sell that info to interested parties, slowly they are going to get intrusive.

Before you use Google's open DNS, try this-

Find your ISP's DNS server IP addresses, and ping them - find the delay in ms
Ping 8.8.8.8 and see the delay

The delay for me is about 6 - 8 times more when I ping Open DNS - this is because my ISP's DNS are much closer than the open DNS servers.

While the millisecond delay is not too long, i dont see how the open dns can make things faster when reaching the server itself is taking a longer time than my ISP's DNS.

Disclaimer! i'm not for or recommending anything. Just my observations. YMMV

It's not about speed. Can't recollect the number of times the dataone's dns server (my home isp and ex-office) has failed to resolve. Problem immediately solved by OpenDNS.

They offer protection against a lot of threats also by blocking domains.
read on here: OpenDNS > Solutions > Overview

Well does your isp keep it's dns servers update?

response to google's dns service is here
OpenDNS Blog

AND google, the monopoly of the net, WILL try to control your internet!

^^^ In short, the service that maps the URL you type to the IP address. If it wasn't there, you'd have to remember and type in 96.30.20.23 instead of team-bhp.com. Try it and see...

it is somewhat like a telephone directory for computers. For example if i want sahil's number i will call up telephone enquiry (directory). If the directory has your number, all fine, otherwise it will direct me to another directory which probably has your number and so on...in computers too same happen. When i type http:// xyx . com/ a dns (directory) helps your computer find the number (ip address) of xyz . com computer.

I'm not sure why people are posting ping times to team-bhp as a reference, instead of pinging the DNS server.

For me, Google DNS 130ms ping is about 25ms faster than OpenDNS.

Absolutely true! If it was about speed, not much would be able to beat your ISPs DNS servers. (eg. Ping to MTNL DNS server is 25ms whereas Google DNS is 130ms)

The reason people switch is for more consistency and less problems.

LOL, so true. The best way to check the effectiveness of a DNS server is to:
1) Try making changes to a domain you control and seeing how long it takes to get them updated.
2) Pinging them directly, though that will only check ping times, not DNS response times.
3) Try quirky URLs, something like TO. -- Get Shorty URL

Exactly! I have often suspected that BSNL's DNS servers often have high response times, which nullify the shorter ping time.
