Up to 24 only is recommended by Solaris doc (based on RFC 952?):

RFC 952 is upgraded by RFC 1123:

2.1 Host Names and Numbers

The syntax of a legal Internet host name was specified in RFC-952
[DNS:4]. One aspect of host name syntax is hereby changed: the
restriction on the first character is relaxed to allow either a
letter or a digit. Host software MUST support this more liberal
syntax.

Even text from docs.sun.com link you posted states on the end this:

"RFC 952 has been modified by RFC 1123 to relax the restriction on the
first character being a digit."


And ... please, strip off non-needed quoted text and signatures when
replying. It helps to make USENet posts much more readable for people.
Thank you.
