[Pdns-users] Multips subnets in one Reverse Zone

[rob777]

Hi

I have a theoretical question which i'm unsure about after AI und Forum
research.

- i have 300-400 IP Subnets (mostly /24 Subnets in 10.0.0/8 CIDR)
- The devices in these 300-400 Subnets have A records in a internal
Powerdns Zone internal.mydomain.com
- There are not that much devices in these Subnetzs (total between
2000-3000 Devices/A-Record)
- Until now we didnt have PTR Records in Reverse Zones for these internal
records
- We are thinking about configuring PTR Records for these internal devices
in 300-400 Subnets
- But if possible we would not like to have 300-400 Reverse Zones but
instead having one single Reverse Zone 10.in-addr.arpa for all the devices
in the subnets

So then having one PTR Zone 10.in-addr.arpa with entries like

5.20.0.10.in-addr.arpa. IN PTR test.internal.mydomain.com.
4.0.2.10.in-addr.arpa. IN PTR ab.internal.mydomain.com.
11.25.0.10.in-addr.arpa. IN PTR cc.internal.mydomain.com.
etc.

So about 2000-3000 such PTR Records in one PTR Zone..

Question:
- Is it possible with Powerdns
- And if yes: would you do it with regards to "Best practice" (probably
not...)


P.s i dont use any delegations on these internal Powerdns Servers
