#37 Different nameservers for different clients/subnets

[Odd Arne Beck]

We've tried to use ipplan in our network just for network documentations but we have problems with the DNS-requests for the different subnets.

Our network is fairly complicated and we have different nameservers for a few class B networks.

(172.20, 21, 22, 23, 24, 25) and all these B-classes have separate domains / DNS-servers.

It would be nice if I could assign DNS-servers to specific subnets.

DNS-Server-A = 172.20.0.0/16
DNS-Server-B = 172.21.0.0/16
DNS-Server-C = 172.22.0.0/16
DNS-Server-D = 172.23.0.0/16
DNS-Server-E = 172.24.0.0/16
..and so on..

When the subnet-scan queries f ex 172.22.0.0, DNS-Server-A can't answer because it doesn't contain the PTR records, these are held by DNS-Server-C.

Thus the subnets contain no hostname because the wrong DNS-servers are queried.

If I could assign dns-server (groups) to subnets, then the documentation of the different subnets would work as a charm.
