Do they?

What I've seen here that *works* is "query the RIPE DB for the published
route(6): objects for a given AS number, and accept that".

What I've seen that does *not* work is "believe if the customer tells you
that they own a given network" - one /24 out of my address space was
announced by a foreign AS, and their upstream *opened up* their filters
to permit it, because the customer called and yelled at them...

I'm not aware of any IRRDB *that is properly authenticated* that is not
run along the RIR hierarchy - RADB is nice, but since anyone can register
anything there, it's worthless for actual verification against purposeful
misdoings (or sufficiently advanced fat fingers).  

RPKI is another option - using RIR hierarchy.

That could be done, yes.  Using the PKI tech for "DNSOA" certification -
but that smells like much more effort than to just run the DNS servers :-)

I agree with you - but still it's enormously comfortable to use the
existing knowledge about address space ownership :-)
