Ok.  What am I doing wrong?  As far as I know this has worked for years

This is for doing > /24 (greater in cidr smaller in size)
Example: we have a /25 that we host... and another /25 we host.. so we
split it up into smaller files unless we own the entire/24


The config is loaded.
Rndc reload reports all is well.
But a lookup fails.

Help?


BIND 9.9.3-P1 on Linux

== included file in named.conf
zone "128/27.1.10.10.IN-ADDR.ARPA" {
          type master;
          file "/usr/named/rev/10.10.1.128.rev";
};
Do you also have a 1.10.10.in-addr.arpa zone, and does it have all the
necessary CNAME records pointing x.1.10.10.in-addr.arpa to
x.128/27.1.10.10.in-addr.arpa?


I do not. 10.10.1.128/27 is a RFC1918 sample. In a real-world example I also have some ATT address space 12.44.51.192/27 or so.. They point it to me.

If I host a partial class, in this case 10.10.x.x I need to have a parent file that cnames?
    Am I correct I would do something like the following...


    $GENERATE 128-160 $ CNAME $.128/27.1.10.10.IN-ADDR.ARPA.



What about when the block is already cnamed -> pointed -> delegated to my host from an external source?

    I tested this.  It appears to be true.  Interesting.


So that would suggest any time any block > a /24 is hosted you must actually host the parent zone, pointing to the larger cidr, and then have your normal files for each cider in that block.
