Public DNS services

Many of you have heard about DNS services.

The main purpose of a DNS server is to enable people and applications to lookup records in DNS tables. Most DNS servers are now private, meaning that they are configured to only provide service to the people and organizations who own and maintain them.

A few domain name servers on the Internet provide DNS resolutions for anyone who requests it of them. These are known as "Public DNS Servers."

In simple language
Basic purpose of DNS is just to get IP address from the domain name like if I type "http://google.com" it will send http://209.85.231.104 to get index/default page from that particular site and DNS is made to make user easy as it's better to remember google.com instead of remembering 209.85.231.104


Every website URL has an IP address. Computers talk to each other using the numeric IP address, while us humans remember the address based on the URL.

I got following conclusion from "GOOGLING"
I am just using OpenDNS and I am very happy with it.. it's pop up updates are irritating else it's good

OpenDNS is good for content filtering.

Comodo Secure DNS and Clearcloud are good for malware and phishing detection

FoolDNS is good for privacy concern as it deletes the cookies and all after your surf..
