Probably true, but not relevant to the discussion. The idea is to force imple
menters to look at the registry so that they see *future* additions to it, ev
en if they get there from reading this RFC-to-be.
You can't force anyone to do anything. If this was split in two (one part
saying look in registry and the other half saying this is the priming list)
it still wouldn't help as developers may just read the second document.
A tentative suggestion: maybe lists of this sort ought to be distributed
via the DNS itself, with nameserver software encouraged to fetch them
dynamically and act accordingly. Something along the lines of
local-zones.arpa. PTR 0.in-addr.arpa.
PTR 127.in-addr.arpa.
PTR 254.169.in-addr.arpa.
...
PTR 8.e.f.ip6.arpa.
PTR 9.e.f.ip6.arpa.
...
Not that this would stop some implementors fetching the current value
and fixing it in their code...
One would want local.zones.arpa (or whatever) to be signed, of course!
