Some of you might be wondering, so what is a DNS Server and what can it do for me?
DNS stands for Domain Name System. You can often notice that using a third-party DNS Server will help improve your browsing experience. DNS helps you increase your browsing speed (and not your downloading speed), the time it takes to load a web-page are often improved using third-party DNS services such as Google & OpenDNS, but that isn’t always the case as sometimes your ISP may provide better DNS than these third-party ones.
The simplest task of a DNS is to translate host names such as (google.com) to a ip address like (22.214.171.124). But most of the third party DNS Servers provide more functionality and are much more secure and up to date than the DNS server of your ISP. They are dedicated DNS servers and well designed for handling all sorts of complicated DNS tasks and requests. So these third-party DNS servers can offer just more than the basic DNS functionality. Many use third-party DNS Services to bypass website block or censoring by your internet service provider.
For example: When your ISP blocks your favorite website (such as Facebook or Twitter), you can trying using third-party DNS to bypass that block (but remember that it does not always work); or if you know the IP Address of the desired website you can use that to access the website, but then again that doesn’t always work either.
ping www.google.com or just
The Command prompt will resolve the IP for the hostname when you ping it.
