Every website on the Internet gets a unique IP address. The IP address is the original place where you can find that website. Initially, people could access a website only by typing its IP address in the address bar of a browser. But remembering the IP address was not easy for human being. So, they started using domain names. The domain name is the alternate address of a website. For example, you need to type google.com to access it.  Now, think if you needed to remember its IP address. That could be impossible. As I said, domain name is an alternate address and Internet still works on IP address. So, all our domain requests are being mapped to IP addresses by DNS servers. It means, it still uses the IP address to connect us with a website.

How does browser know what IP to open for a domain name?

The answer is DNS server. DNS server plays an important role in web browsing. It keeps records of IP address and corresponding domain name. In this article I will talk about DNS server and its effects on web browsing. I will also share a list of best public DNS servers that are free to use and improve web browsing by offering faster page load.

What Is A DNS Server?

DNS stands for Domain Name System that maps IP address with a domain name. When you type google.com, requests for go to DNS server that resolves the request to IP address. The request goes to that IP address for getting the response from the server. Servers that resolves a domain name to IP addresses are called DNS servers. ISPs either use their own DNS servers or partner with any good DNS service providers.

This photo will make it clear how a web browsing request uses DNS server for giving us access of the website.

DNS does not directly affect your web browsing or Internet speed, but it can influence how fast a web page appears on your computer. It does not affect download speed but It affects the web browsing. Now you now know that the time is taken in a web page loading also includes the time taken by DNS server response. If your ISP starts using a fast DNS server in place of its own DNS server, your browsing can be improved. Faster DNS servers respond faster andsaves few mili seconds of web page loading.

There are several public DNS servers that offer faster results as compared to default DNS server of your ISP. If you manually configure your router or system to use any of the fast public DNS servers, you can improve your web browsing.
