I disagree, it will respond with the FIRST entry in the database. If the database contains somename before news, it will respond with somename. If news appears before somename, it will respond with news. This is especially true if the responses are comming from a secondary server. It will cause you headaches because the machine's identity if ever checked by reverse address lookup may sometimes fail.
