So this is is really the question I had, and this is why I was wanting to
start a dialog here, hoping that it wasn't out of line for the list. I don't
know of a way to let a bunch of operators know that they should remove
something without using something like this mailing list. Blacklists are
supposed to fill this role so that one operator doesn't have to try and
contact thousands of other operators individually, he/she just has to appeal
to the blacklist and once delisted all should be well in short order.
In cases where companies have their own internal lists, or only update
them a couple of times a year from the major lists, I don't know of another
way to notify everyone.
I suspect you'll find many of the private "blacklistings" are hand
maintained (added to as needed, never removed from unless requested) and
you'll need to play whack-a-mole, reaching out to each network as you find
they have the space blocked on their mail servers or null routed on their
networks. I doubt your message here will be seen by many of the "right
people." How many company mail server admins read NANOG? How many
companies even do email in-house and have mail server admins anymore? :)
Back when my [at that time] employer was issued some of 69/8, I found it
useful to setup a host with IPs in 69/8 and in one of our older IP blocks,
and then do both automated reachability testing and allow anyone to do a
traceroute from both source IPs simultaneously, keeping the results in a
DB. If you find there are many networks actually null routing your
purchased space, you might setup something similar.
