domains is this website. It provides all of the information related to the domains I own. I try to keep everything as organized as possible. This is why there is the domain name, and a separate page for the domain extensions. All of the sites you wish to learn about, and their role is in this domain. This domain however, like most of my domains, is only 1 website (this site), and therefore there is no need to expand on adding subdomains within this domain.
