DNS bind, adding sub-netted reverse look up zones

Hi,

Could any one tell me how to add a single reverse look up zone in Red hat for a /19 network

I know you can add multiple /24 class-full subnets. but I also know you can add variable length subnets.

so could any one point me in the direction of the correct syntax for RedHAT?

Cheers

This should show you how to configure bind for VLSM.

I have tried the standard

zone "0/19.x.x.x.in-addr.arpa" {
type master;
file "zone.0-19.x.x.x.in-addr.arpa";
allow quesy { any; };
};

and it loads OK but does not seem to catch any thing.

zone "0/19.x.x.x.in-addr.arpa" {
type master;
file "zone.0-19.x.x.x.in-addr.arpa";
allow quesy { any; };
};

One problem I see with the above is in bold.

Should be like...

allow-query { 127.0.0.1; net; };

that "any" works fine for our other reverse zones

Dispit trying a few different syntaxes I just can't get it to work.

I have looked around at other sites to see if I can find anything different, and all signs point to this working. I will keep looking.

Thank you for all the help, but reserching further and it does seem you can only use the subnet mask on subsets of a class C network, no swhere have I found any thing to show examples of class B or above
