What Is DNS and Why Is It Important?

DNS (Domain Name System) acts as the phonebook of the internet—it translates domain names into IP addresses.

When you type a URL like example.com, DNS servers direct your browser to the correct web server.

Poorly configured DNS can slow down your site or cause downtime. Tools like Cloudflare help manage DNS for better speed and protection web hosting for developers.

A fast, reliable DNS setup also contributes to better SEO and user experience.

Understanding DNS is crucial for anyone managing a website or migrating hosts.
