What Is a DNS Server?

The DNS protocol is very crucial part of the web’s infrastructure, serving as the Internet’s phone book: every time you open a website, your computer performs a DNS lookup.

Complex pages often require multiple DNS lookups before they start loading, so your computer may be performing hundreds of lookups a day.

Each website on the Internet has a 12 digit number (IP Address) that your computer needs to know in order to make contact.

When you try to open website in a browser, your computer queries the assigned DNS server, the DNS server reports the IP address back to you, and the computer starts a connection with the website you requested.

All these activities are going on in background, and so you don’t need to know about DNS to use it. Most people are using a private DNS server that’s assigned by their ISP; however, there are many open (public) DNS servers such as Google DNS server. and Open DNS.
