Domains and subdomains

Obviously when looking at a subdomain ( it is easy to figure out the top level domain ( My question is . . . without being told about or linking to a subdomain how difficult is it to find a subdomain under a top level domain? For example if I wanted to make “” and put birthdays, phone numbers and such on a subdomain can some one that was not told about it, find out about it? How? Would there be a better way to execute my example?

Thanks for the help,

Watch out for search engines.

Try a Google search on ‘ -qxxxxxxx’ and watch the results include subdomains of

Thanks for the info. It is always simple when you know what to do, and you did.

Guess I’ll have to use some kind of password for a page.

Thanks again,
