[arin-ppml] Draft Policy ARIN-2014-12: Anti-hijack Policy

So if my understanding is correct, they basically performed a routing man in the middle attack on live IPv6 prefixes. Pardon my understanding level, but how did they keep from creating routing loops and service interruptions. I'm also a little concerned about performance and link loads. Are my concerns legitimate and inline?

I read some more of that article I sent.  They specifically state that they had LOAs from the RIRs to do these /12 advertisements.

There is a paper here

that says
"We announced the prefixes: 2400::/12, 2600::/12, 2800::/12, 2c00::/12, 2a08::/13, and 2a04::/14 for over a three-month period. For a few days, we also announced RIPE's 2a00::/12"

So I believe that the answer to your question is yes.

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'm the primary shepherd for this Draft;

The author is Heather Schiller, and I'm only saying that because I'm going to reference you to her comments at the mic at the last NANOG.

The research that prompted the proposal was presented at the last NANOG in Atlanta and is at the following link;


Heather's comments begins at about time stamp 17:10 or so on the video of the NANOG presentation, and there are a couple other comments as well.

Additionally, the reference for the published paper for the research in question is;




[Shepherd hat - OFF]

While I do not have a problem with this research and I don't think we should restrict future such activities, I believe this is something the community should discuss in detail and try to come to consensus on, one way or the other.

Also, while I disagree with the proposed policy text, what is proposed is not without precedent.  As discussed in the NANOG presentation, RIPE initially gave permission for a covering prefix for its whole /12 and then it was modified to a covering prefixes of a /14 plus a /13, excluding the space where most allocations were.  This significantly reduced the amount of traffic for RIPE region and they were excluded from the analysis.

Hope that helps.

I issued and managed almost every experimental assignment for almost 10 years from 2003 to 2013, and I am lost as to what this policy is saying.  I would like to be educated so I can support, or not support, the efforts that have been made here.

> ARIN should not give research organizations permission to hijack prefixes that have already been allocated. Research organizations announcing lit aggregates may receive sensitive production traffic belonging to live networks during periods of instability.

> Modify the section 11.7 heading to be more accurate. Modify the first sentence to prohibit overlapping assignments. Add text at the end to define how research allocations should be designated and prohibit LOA's without allocations.
> 11.7 Resource Allocation Guidelines
> The Numbering Resources requested come from the global Internet Resource space, do not overlap previously assigned space, and are not from private or other non-routable Internet Resource space. The allocation size should be consistent with the existing ARIN minimum allocation sizes, unless small allocations are intended to be explicitly part of the experiment. If an organization requires more resource than stipulated by the minimum allocation sizes in force at the time of their request, their experimental documentation should have clearly described and justified why this is required.
> All research allocations must be registered publicly in whois. Each research allocation will be designated as a research allocation with a comment indicating when the allocation will end. ARIN will not issue a Letter of Authority (LOA) to route a research prefix unless the allocation is properly registered in whois.
