Legal hostnames for the longest time have been defined by RFC 952.

start with an alphabet character
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), minus
sign (-), and period (.). Note that periods are only allowed when
they serve to delimit components of "domain style names". (See

name. No distinction is made between upper and lower case. The first
character must be an alpha character. The last character must not be
a minus sign or period.
