Search Again: Re: reverse DNS zone loop problem From: Men & Mice Support Date: Monday, January 12, 2004 Time: 12:24:33 pm There is no set naming convention for how this type of delegation is done. The RFC that describes classless subnet reverse zones makes a suggestion, but it also denigrates its own suggestion. Your new ISP uses a different convention than your old one did. You must abide by that. Export the zone, then re-import it using the correct name, which is "0/27.67.8.151.in-addr.arpa". Then presumably, once the class B subnet issue (discussed by Len) is corrected, it'll start working. ____________________________________________________________________ Chris Buxton Men & Mice Customer Support Specialist Making DNS Easy At 9:40 PM +0100 1/12/04, Gabriele Polidori wrote: >Hello, > >we have a problem with our reverse zone, apparently. >My ISP delegated to us the zone 'onenet.it' so I also created the >reverse zone file (which also should be delegated to us). > >Now, it doesn't work; I checked it with www.dnsstuff.com and there' s a >loop between our dns (dns.onenet.it) and the authoritative NS for the B >class (ns.iunet.it). >There's also a loop between our 2 name servers. > >I'm sure there's something wrong also because our mail server >(mail.onenet.it, it's EIMS), which is on the same IP as dns.onenet.it, >doesn't get the proper name. >In the TCP I put the IPs of our own dns server, plus an ISP dns (do I >have to take it off?) > >Our master is dns.onenet.it 151.8.67.20 >our slave is dns2.onenet.it 151.8.67.22 > >We have 151.8.67.1 to 151.8.67.30 > >I named the reverse 0-31.67.8.151.in-addr.arpa.
