What is a domain?
A domain is your website's address (e.g. 166tech.az). Technically it's a name for an IP address — computers use IPs, humans use names.
How does it work?
- Type "166tech.az" in browser
- Browser asks DNS: "what IP is 166tech.az?"
- DNS responds: "72.61.205.54"
- Browser fetches site from that IP
