Domain Name System

DNS translates domain names to IP addresses

The Domain Name System (DNS) is crucial for translating human-friendly domain names into numerical IP addresses, enabling users to easily access websites and online resources. This translation process is fundamental to the Internet's operation, allowing users to navigate the web without needing to memorize complex IP addresses. The DNS system also ensures that the Internet remains scalable and efficient by distributing the responsibility of name resolution across multiple servers, rather than relying on a single central database.

Example

When you type "www.google.com" into your browser, the DNS translates this domain name into its corresponding IP address, such as 172.217.12.36, allowing your browser to connect to Google's servers and display the website.

Remember this

Understanding DNS resolution is essential for grasping how the Internet functions and how websites are accessed by users.
