[dns-wg] sub-/24 "delegation" [2014-01 New Policy Proposal (Abandoning the Minimum Allocation Size for IPv4)]

Dear Eric,

I may be wrong, but my understanding is that this I-D focuses on storing and
retrieving information associated with a given (known) IP address range.
Such information could be related to BGP routing, IRT and abuse, secure mail
servers, etc.

The problem I see here if you want to use this naming convention for
"traditional" reverse queries is that you have to _know_ the address block
you are trying to find information about, before starting the query.

In case of a "traditional" reverse query for 192.168.1.1 for example, in
order to use the above approach one would have to first query the RIR database
(or perhaps some other place?) to find out the assignment the given IP address
belongs to (e.g. 192.168.1.0/25) and _then_ we could query something like
1.0.m.1.168.192.in-addr.arpa.

Did I misunderstand the I-D?

Best regards,
Janos
