No. You shouldn't have a file for <29.100.209.in-addr.arpa.> at all - that's your provider's job. Fortunately, once he tells you how he wants to handle classless delegation, you can just change the name of the zone (in the Domain Info dialog) to have all your records corrected automatically. If he's really following the example procedure in the RFC, the zone name will be changed from <29.100.209.in-addr.arpa.> to <128/25.29.100.209.in-addr.arpa.>. >One of my providers currently creates a "shim domain" for my inverse dns >which requires that I name may inverse files as follows: >mia-1.xxx.xx.xxx.in-addr.arpa. , mia-2.xxx.xx.xxx.in-addr.arpa. , etc... > >If this makes sense please help shed some light on this... Thanx, It does indeed make sense. If you feel comfortably fluent in technobabble, you can try reading the RFC in question: <ftp://NIC.MERIT.EDU/internet/documents/rfc/rfc2317.txt>. Tell your provider you'd like to go ahead with classless delegation. After he finishes setting up his end, query his name server for a CNAME record for <129.29.100.209.in-addr.arpa.>. This will show you what zone name to give your file. If you need further help with this, just ask. It's not an easy thing to understand (or to explain), but it's fairly easy to set up once you get it. ____________________________________________________________________ Chris Buxton Men & Mice cbuxton@menandmice.com http://www.menandmice.com
