by Adding Domains
The newly added domain will share the subscription’s resources with all other domains belonging to the same subscription. However, in all other respects the newly created domain will be independent from the principal one – it will have its own web hosting and DNS settings, databases, mail accounts, and so on.
To add a new domain, go to Websites & Domains > Add Domain.
Adding Subdomains
If your subscription allows it, you can create one or more subdomains, or third-level domains, for each of your domains. Subdomains share all the subscription’s resources with all the other domains and subdomains belonging to the same subscription. However, every subdomain can have its own web hosting and DNS settings.
To add a new subdomain, go to Websites & Domains > Add Subdomain.
