DNS or Domain Name System, helps resolve the name of any web address. When you type a domain name in your browsers address bar, say www.TheWindowsClub.com, your computer resolves this name into the IP address of the Internet server, where the site is hosted, using the Internet Protocol.
The Windows operating system, is set by default, to automatically use the DNS server of your ISP or Internet Service Provider.
A slow DNS server could be one cause for poor web browsing speed. If your ISP’s DNS server is slow, or responds slowly, or at times is overloaded, it may cause an additional delay of a few seconds, every time you go on to load a new web page.
While is most cases, keeping the default option is a good idea, if you find that your default DNS provider is slow, you may want to consider finding one that is fast. To test the response time for your DNS server, you can use Dig. It is important to know that what may be good for one person in one part of the world may not necessarily be good for another person sitting in another part of the world.
This is where you can consider alternative 3rd-party DNS providers like OpenDNS, UltraDNS, Google DNS etc. Do however note that one must consider using a reputed and a reliable DNS server only, as such providers offer a better browsing experience, provide protection from phishing sites and refresh their DNS records faster when website change their IP addresses or new domains are registered.
