How DNS Works

When you type a domain name into your browser, it doesn't instantly know where to take you. That's because computers only understand IP addresses. So, it has to make a request - to ask another computer (a DNS server) which IP address matches the domain name you just entered.

Often, if it's a site that gets looked up a lot, the server knows right away. The reason behind this is that each time it performs a DNS lookup, it saves the IP for a certain time in its own memory. This is called the cache which plays a signifact role in making DNS run smoothly.

Below is a simplified process of what a DNS does:

  1. The DNS server will look up and send to the nameservers that are associated with the Domain Name that you have entered in your browser.
  2. Your Hosting provider, which is in-charge of managing your nameservers, will then forward the nameserver request to the server where your website’s files are stored.
  3. The web server will then gather the requested information and send it back to the web browser to display your website.

As you can see, there are a lot of things undergone behind the scenes to make your domain work and display your website.
