Domain

A domain is the human-readable address used to identify a website on the internet. Instead of typing an IP address, users enter a domain name such as example.com to reach a site. Domains make navigation easier and form the foundation of online branding.

Domains are structured hierarchically. They consist of a top-level domain such as .com or .org, a second-level domain chosen by the owner, and optional subdomains such as blog.example.com.

Advanced

Domains are managed through the Domain Name System (DNS), which translates domain names into IP addresses so browsers can connect to the correct server. Domains must be registered with accredited registrars and renewed periodically.

Management often involves DNS records such as A, CNAME, MX, and TXT for routing traffic, managing email, and verifying ownership. Businesses also secure multiple domains or variations to protect their brand.
