The Domain Name System (DNS) is often called the “phonebook of the internet.” Its job is to translate human-friendly domain names (like cloudstorie.com
) into machine-readable IP addresses.
When a user enters a domain name, the DNS system quickly matches it with the correct server’s IP address and delivers the website content. Without DNS, you would have to remember long strings of numbers instead of simple names.
Key parts of DNS include:
- DNS Resolver – Receives the request from the browser.
- Root Server – Directs the query to the correct top-level domain (e.g.,
.com
). - Authoritative Server – Provides the final IP address for the domain.
A properly configured DNS ensures your website is always reachable. Misconfigured DNS settings can cause downtime, slow loading, or even security issues.
