What Is A DNS Server?
DNS (or also known as Domain Name System) is a system that matches domain names like Google.com or Yahoo.com to the right IP addresses. This system is a database of domain names and IP addresses. It has been using to maintain a directory of domain names and helps to translate these domain names to the right IP addresses.
Domain names are the human-readable addresses that we are using every day. For example, the domain name of Yahoo is yahoo.com. If you want to visit Yahoo’s website, just enter Yahoo.com into the address bar of your web browser.
But, your computer does not know where “yahoo.com” is. Behind the scenes, your computer will contact DNS servers and ask what IP address is associated with yahoo.com.
After that, it will connect to that web server, load the contents and display in your web browser.
In this case, Yahoo.com is located at the IP address 188.8.131.52 on the Internet. You can type this IP address in your web browser to visit Yahoo’s website. However, we use “yahoo.com” instead of 184.108.40.206 because it’s easier to remember.
Without DNS, the whole Internet will not be accessible. We will be back to the time that the Internet wasn’t born yet. And your computer can only use to compose documents or play offline games.
Of course, it’s just a simple explanation, in fact, it’s a bit complicated. For further information, I would recommend you to read this article or watch the below video.
