DNS (Domain Name System) is a system that converts website names into IP addresses. It allows people to use names such as google.com instead of remembering numbers.

When you enter a website address, DNS helps your device find the server hosting that website. It works like a phone book for the internet, matching domain names with their corresponding IP addresses.

How It Works

• You enter a website name in your browser.
• Your device sends a DNS request.
• A DNS server finds the matching IP address.
• The address is returned to your device.
• Your browser connects to the website’s server.

Common Uses

• Finding websites on the internet.
• Connecting devices to online services.
• Resolving domain names into IP addresses.
• Supporting email delivery.
• Managing names for private networks.
