DNS stands for Domain Name System. It helps users visit websites without needing to know IP addresses. Users type in domain names, like www.example.com, while web browsers use IP addresses to find those websites. DNS translates the domain name into an IP address so that the browser can connect to the site.
There are many devices on the internet, and each has its own IP address. Devices use these addresses to recognize each other. DNS makes it easier for users by letting them use domain names instead of remembering IP addresses. This is helpful because IP addresses, whether IPv4 or the newer IPv6, can be hard to remember.
Whenever you search for something online, DNS works behind the scenes to help connect you to the website without you needing to think about the IP address.
