Overview

A domain name is useless without the Domain Name System (DNS), which acts as the high-speed translation engine connecting human text requests to machine hardware.

The Resolution Process

• User Request: A user enters a domain name into a web browser's address bar.
• Cache Check: The browser and local operating system check their internal caches to see if they have recently resolved that domain to an IP address.
• Recursive Query: If not cached locally, the request queries a recursive DNS server (typically operated by an Internet Service Provider or public resolver like Cloudflare or Google).
• Authoritative Lookup: The recursive server queries root name servers and TLD name servers until it locates the authoritative name server designated for that specific domain.
• Connection Established: The correct numerical IP address is returned to the user's device, enabling the browser to securely load the web page from the hosting server.
