Hi List I use Powerdns Authoritative with Powerdns Recursor for Internal Zones. Currently i have 300-400 Subnets in the 10.0.0.0/8 Range. Currently i have only for 3 Subnets in this Range a Reverse zone configured in my Pdns Auth. and PDNS Recursor. So i have...
10.0.10.in-addr.arpa 10.0.20.in-addr.arpa 10.0.25.in-addr.arpa ....configured on the PDNS Auth. And the following in my PDNS Recursor - zone: 25.0.10.in-addr.arpa forwarders: - 10.0.50.100:5300 - zone: 10.0.10.in-addr.arpa forwarders: - 10.0.50.100:5300 - zone: 20.0.10.in-addr.arpa forwarders: - 10.0.50.100:5300 I would like to migrate the Reverse zones so that i have a single "Catch all" Reverse zone for the whole 10.0.0.0/8 Nets which will be then used for all 300-400 Subnets so: 10.in-addr.arpa My question is now how can i softly migrate this? My idea is: 1. create a new reverse zone 10.in-addr.arpa and starting to fill it with records (and dont yet configure it in the Recursor Forwarde-zones config...) 2. If i'm ready with 10.in-addr.arpa Zone -> reconfiguring the pdns-recursor forward-zone config to - zone: 10.in-addr.arpa Reverse forwarders: - 10.0.50.100:5300 3. deleting the existing forwarding to the 3 existing 10.0.10.0/10.0.20.0/10.0.25.0) Reverse Zones Would this work or will this generate a conflict with the existing 10.0.10.in-addr.arpa, 10.0.20.in-addr.arpa, 10.0.25.in-addr.arpa Reverse zones? Or will Powerdns Auth. not be able to load this new reverse zone 10.in-addr.arpa because it overlaps with regards to subnets of the already existing three single reverse zones in this same range? Or can i safely create the 10.in-addr.arpa Reverse zone, configure all records in it and then change the Forward zone file? And afterwards safely deleting the three single reverse zones in the 10.0.0.0/8 Range? Best Regards
