When you purchase a domain name, you can have “subdomains”, basically <anything>.yourdomain.com. They can be configured as separate websites or the same website – configurable to your liking.

Examples, if you purchased yourdomain.example.com you can have:

• andy.yourdomain.com

Interesting note: “www” is just a subdomain. Your website can be configured not to respond to www.yourdomain.com.
