Something like the following will match anything prefix'd with `admin`.
You'd have to include the suffixes manually.  Luckily, there aren't too many
tld's for this to be a major concern.

^admin\.[^\.]+\.(?=(com|net|org))$

You can capture the entire hostname by including grouping operators
around the entire regex:

^(admin\.[^\.]+\.(com|net|org))$
