dashes only.
"The Internet standards (Request for Comments) for protocols mandate that
component hostname labels may contain only the ASCII letters 'a' through 'z'
(in a case-insensitive manner), the digits '0' through '9', and the hyphen
('-'). The original specification of hostnames in RFC 952, mandated that labels
could not start with a digit or with a hyphen, and must not end with a hyphen.
However, a subsequent specification (RFC 1123) permitted hostname labels to
start with digits. No other symbols, punctuation characters, or white space are
permitted."
Per Wikipedia's 'Hostname' entry.
