Comment 2 Ryan McCabe 2008-02-26 17:44:25 EST
Underscore is not a valid character in a hostname.

From RFC 952 (http://tools.ietf.org/html/rfc952):
  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 (.).
