According to wikipedia.org,
The Domain Name System (DNS) is a hierarchical distributed naming system for computers, services, or any resource connected to the Internet or a private network. It associates various information with domain names assigned to each of the participating entities. Most importantly, it translates domain names meaningful to humans into the numerical identifiers associated with networking equipment for the purpose of locating and addressing these devices worldwide.Well, that's a mouthful. Albeit too technical for most of us.
DNS serves as a phone book to the World Wide Web which maps out each connected device to the global network. It manages the name of our websites so we and other people can access them by typing them in our web browsers. That is why we can only have one specific address that we can use in naming our websites. Duplicate domain names are not allowed to avoid problems in accessing our web pages.
Our computers acts as hosts to each incoming connections and also works as clients to other computers in the Internet. Some computers works as DNS servers to provide us with a better network directory and reach our desired destination. That is why replacing your default DNS server address can make a considerable impact on how you browse the Internet.
- It can increase your Internet speed. (though this will vary on other factors eg. PC specs, subscribed Internet speed)
- It can lessen or completely resolve your selective browsing issues
- It can give complete control on how you browse the Internet on your network by using filters (like that of OPENDNS)
The desired DNS addresses (my preferred and tested lists):
|Google's Public DNS||22.214.171.124||126.96.36.199|
|Destiny Cable Internet||188.8.131.52||184.108.40.206|
What's left for us to do now is to make use of these numbers and start punching them in our PCs and see if they do work. I have tested Google's Public DNS and OpenDNS as well.
I prefer Google's DNS addresses since it has never failed me to access most of my frequently visited websites (and it is faster than that of my ISPs). OpenDNS on the other hand served me a different purpose. That is, filtering my Internet Cafe's access to some of the restricted sites in the web :) (You know what I mean!)
