What is a DNS server?

Question

Hello, What is a DNS server, and how does it work in resolving domain names?

Answer 1

A DNS (Domain Name System) server is a system that translates human-readable domain names (like example.com) into IP addresses (like 192.0.2.1) that computers use to identify each other on the internet.

When you type a URL in your browser:

1. Your computer asks a DNS resolver to find the IP address for that domain.

2. The resolver queries other DNS servers (root, TLD, authoritative) to get the correct IP.

3. Once the IP is found, your computer can connect to the website.

Without DNS servers, we would need to remember complex IP addresses instead of easy-to-use domain names.
