To me, an NXDOMAIN-reply seems better than an answer with an A-record to 127.0.0.1 (because that won't be an incentive to fix an apparently broken situation). My advice: forget about localhost entries in your zone files, unless it concerns a special situation, such as domains that are part of your search-list. You may want to consider adding it in such a case (although I don't do so). But if you do, don't forget to add an AAAA-record for ::1 as well ;-) Regards, -- Marco
