Search Again: Re: Setting Up Reverse DNS Query From: Men & Mice Support Date: Friday, January 21, 2005 Time: 10:15:33 am You misnamed the zone. Take out 'arpa' - it should be 233.20.212.in-addr.groovychocolate.com. Also, if you haven't done so already, duplicate the NS record from the reverse zone in the groovychocolate.com zone, like this (using shorthand): 233.20.212.in-addr NS ns Furthermore, the zone is delegated to both your server and ns2.pdq.net. If this is what you want, add another NS record to both the reverse zone and the groovychocolate.com zone pointing to this server, and make sure that this server is configured to get the zone from your server. If you don't want this other server hosting your reverse zone, notify ednet.co.uk of this. They should be willing to remove the NS record from the delegation, though they may insist that you find some other server for the zone (so that there are at least two).
