Topic: DNS forwarder: How to control reverse DNS?  (Read 3034 times)

Hello....

I'm using DNS forwarder to name various servers. Some servers have more than one DNS. Is there a way to control how reverse DNS resolves? Now, it seems to resolve to the first name sorted by alphabetically.

Thanks,
Tobias

I don't know of any option on how to control this, or what the correct way to resolve it would be , other than a control by source ip running the query ?

Can you be more specific? I don't really understand. Are you suggestion changing the code on the Monowall?

Thanks

The change would have to be in the DNS  (dnsmasq) , but I don't know what your desired operation is.

If I have 2 PTR records like

192.168.1.10 myserver
192.168.1.10 myothername

and the client asks for a resolve of 192.168.1.10, what name do you think it should return and why ?

 What I would like to do is to be able to choose between "mynameserver" and "myothername" in this case. As it is now, it is undefined (Or, at least unknown to the administrator).
