Here is how to establish DNS services on OS X Server; that's for 10.6, but — once you check the Show All Records setting in Server.app in 10.7 or 10.8 — it still applies.
To verify most of what can be wrong with the local DNS server configuration, launch Terminal.app from Applications > Utilities, and enter the non-destructive diagnostic command:
sudo changeip -checkhostname
You'll need to enter an administrative password for the sudo, may see a one-time "here be dragons" warning about the use of sudo and that warning message can safely be ignored, then you'll see some data on the host and network configuration, and then an indication whether no changes are required or whether DNS or network changes are likely needed.
What you're looking at is the reverse DNS, and that's based on the subnet and the forward DNS; the reverse DNS is usually automatically added, but I occasionally find I have to clean out the default zones and either manually rebuild things or allow Server.app to rebuild DNS.
thanks for the explanation and the link - i think many things are more clear know.
But one thing still isn't answered.
What is the difference between the Reversezone
22.214.171.124.in-addr.arpa. and 1.0.10.in-addr.arpa
if the ip of the server is 10.0.1.8
Is this one of the zones corret? Both?
The default installation setup — if there's no other local DNS server — traditionally creates a single-host zone, with a reverse zone, and as you clean that out and create hosts in your own zones for your own local DNS domain(s), you'll get one or more reverse zones created, depending on the IP addresses and subnets in use.
Ah, I think I understand my problem.
I have two different servers
"mac-mini.local" (10.0.1.50) and
in my subnet 255.255.255.0 One Public IP Adr. Shared
As I set up the first server i had a reverse zone like 126.96.36.199.in-addr .. and the second was like 1.0.10.in-addr ...
I think I have to combine the servers with better naming rules ... xxx.server.private and than it shouldn't make any troulbes with reverse lookup zone.
