DNS in Web Hosting

-

 



What is DNS?

The internet connects devices, servers, and websites using special numbers called IP addresses. Computers understand these numbers, but it's hard for people to remember them.

In the past, this wasn't a problem because there weren’t many websites. But as the internet grew, it became harder to remember all the numbers. That's when DNS (Domain Name System) was created. It works like a phonebook, changing easy-to-remember website names (like www.servers99.com) into IP addresses. This makes it easier for us to access websites without needing to remember numbers.

How DNS Works

DNS works like the contact list on your phone. When you save a person’s name with their phone number, you can search for their name to find their number. Similarly, DNS translates a website name into a unique IP address.

When you type a website's address in your browser, your request first goes to a "recursive server" (usually provided by your internet service provider). This server checks where the IP address for that website is stored. DNS servers are located all around the world, and the closest one to you helps find the right address.

Once the IP address is found, it is sent back to your browser, and the website loads.

It might be physics . We see it all the time: a business targeting shoppers in Melbourne is running on a "cheap" server based in the US.

A 1-second delay can destroy your conversion rates. This is why "Bare Metal," or a dedicated server , is no longer a luxury, it's a necessity for growth. But ho...
