Hello Mark,
thank you very much for your quick answer.
I'm sorry for express unclear.
Creating of the reverse zone file is good documented and no problem. Both
nameserver are already set up and work fine, except that the queries for the
special subnets are not delegate from the Master to the "smaller" nameserver.
As I try to draft with the little picutre below, I have one registered
nameserver (NS Master) for the whole adress space. This server should delegate
queries for the subnets handelt by the NS Customers to their nameservers.
query from internet

+---+ +---+
| NS Master | delegate| NS Customer 1 |
| 2001:DB8::/32 |-->>>--+-| 2001:DB8:100::/48 |
+---+ | +---+
|
| +---+
| | NS Customer 2 |
+-| 2001:DB8:200::/48 |
| +---+
|
+NS Customer N
The both IPv4 lines should only demonstrate the function I think to need.
As I read the DNAME record could/should be used for delegation. But I find
only further information for map different networks under one reverse file.
best regards
Markus
