That summary of the issue helps a lot, thank you!
The question on my mind is:
Did ARIN provide a written LOA to Merit to announce 2600::/12 ?
I have no direct knowledge one way or the other, I have to defer to ARIN staff
to answer that question. Paging John Curran please. :)
However, In addition to what CJ referenced, the presentation given at RIPE 66 (slide 7)
implies that ARIN and the other RIRs did provide an LOA, doesn't say "written"
but again I think that is implied as well.
Yes, ARIN provided the referenced LOA, which is a bit of a surprise to
me as well.
Here's what surprises me: that it is ARIN's business at all to provide
an LOA allowing someone to announce a BGP route. I could have sworn that
I have read hundreds of times that ARIN is *only* in the business of
running a database in which they maintain unique registrations, and that
routing policy is of no concern to ARIN.
Either ARIN added a database entry assigning 2600::/12 to Merit, in
which case I am confused for several reasons, starting with it not being
a unique assignment...
Or ARIN didn't add a database entry assigning 2600::/12 to Merit, in
which case what could the letter possibly have said?
I'm looking into the details on this now, but here's the
short version of what I know at this point -
ARIN has often cooperated with Merit on darknet research activities, and
this includes providing authorization to enable looking into latent traffic
on space not yet issued by ARIN. Some typical examples that come to mind
include new /8's just received from IANA and the /10 for shared transition
space.
We were asked to cooperate with Merit on darknet research on ARIN's IPv6
2600::/12 space and I authorized the effort. Apparently, the effort also
included the routing an overall covering prefix and I missed that aspect
of the project. Aside from the technical concerns outlined here, there
is also a very valid question of whether ARIN should ever be involved in
routing authorization covering already issued space, since presumably the
same dialogue and consensus in the operator community (that should be a
prerequisite for such an experiment) should also suffice as the approval
with ISPs when it comes to researchers actually inserting the necessary
routes.
I think there's a valid question of whether ARIN should ever be involved
in routing authorization. Full stop.
Going forward, ARIN will not issue routing authorization that covers any
address space issued to others without community-developed policy that
specifically directs us to do so.
I would hope that in the absence of both community-developed policy
*and* a change in ARIN's chartered mission, ARIN would not issue routing
authorization that covers any address space, with the possible exception
of the addresses assigned to ARIN itself for its own servers.
