What is DNS?
While browsing the web, when we call for an URL we actually communicate with the DNS (Domain Name System) server. It is the DNS server who looks for the numerical IP address of that URL and connects us to it. By default we are using the DNS server provided by our Internet Service Provider. And in general this server takes more time to resolve the web address and thus results a slower surfing experience. So the question is, can we shift to a faster server? Yes, here comes OpenDNS...
