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:
- 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.
- 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.
- 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.
