1. A "name" (Net, Host, Gateway, or Domain name) is a text string up
to 24 characters drawn from the alphabet (A-Z), digits (0-9), and the
minus sign (-) and period (.). No blank or space characters are
permitted as part of a name. No distinction is made between upper
and lower case. The first character must be a letter.
