When we enter a web address in our browser (kannani.blogspot.com), our browser doesn’t know where the site kannani is located.
To find the specific address of the site in terms of IP address, the DNS server is contacted first which converts the hostname (kannani.blogspot.com) to ip address (22.214.171.124) which is the exact address of the server which is hosting the site.
In order to be able to retrieve the IP adress fast, the DNS servers i.e the computers which do the conversion must be fast enough but the DNS servers that our ISP's' provide are not fast enough.
This is where OpenDNS comes into action. OpenDNS provides a reliable and faster DNS service and the best thing is it is totally free. They are having their DNS servers located all over the world from which the server which is located near you will be used to resolve your DNS queries.
