DNS

DNS, or Domain Name System, is like the internet’s phonebook. It translates domain names (e.g., www.example.com) into IP addresses that computers use to identify websites, such as 123.456.78.90. Computers use these IP addresses to locate and communicate with each other on the internet.

How Does DNS Work?

When you type a website name into your browser, your computer sends a request to a DNS server. The DNS server looks up the domain name and returns the corresponding IP address, allowing your device to connect to the website. This process isn’t limited to websites—it’s also used for services like email delivery.

DNS simplifies browsing by handling the technical details of finding and connecting to websites, so you don’t have to remember long strings of numbers. It’s an essential part of making the internet user-friendly.
