It is important to remember that it takes time for the subdomain to become recognized by other computers on the web. Visitors will not be able to view your subdomain immediately; the process takes anywhere from 2 days to a week.
Subdomains can be useful for creating unique user accounts for “vanity domains.” This is helpful if, for example, you have a blog, or any other type of website that uses a domain specifically titled for a user.
