The key phrase is "A correctly operating resolving proxy DNS server must discard them ...".
Yes. This is your original complaint about matching apexes with delegations. I am not violating that condition, however.
Now, if you wanted to do separate zone files, and make sure that each zone file doesn't contain any out-of-zone data, that would be a different issue. But this is like handing people sticks of dynamite, flamethrowers, and encouraging them to ignite the explosives they're holding in their hands.
I am doing separate zone files. Each IP delegated to me is a separate zone. Now, again, what is wrong with that?

What A-records is it talking about? I am not seeing any. [axfr is closed] [banter about SOA values] [all servers on the same subnet]

What about this? % dnswalk -ralF 122.109.193.in-addr.arpa. Checking 122.109.193.in-addr.arpa. Getting zone transfer of 122.109.193.in-addr.arpa. from ns2.bit.nl...done. SOA=ns.bit.nl contact=root.bit.nl
[hosts outside my /29] [failed zonetransfers] Nothing there that's wrong with my /29.

This is the parent zone.

[hosts outside my /29] Indeed, you found some things wrong with the /24 zone, but that was not the subject, and nothing you found wrong with the /24 is related to the /29. Greetz, Peter -- peter () dataloss nl | http://www.dataloss.nl/ | Undernet:#clue
