Hijacking

Please excuse me for this rather naive question, but I really don't know the answer. (And in the present context, I would very much like to know.) Do the contracts that various entities, including but not limited to LiRs, sign with RIPE, in exchange for being issued RIPE number reources, include any sort of a stipulation or condition that the parties agree not to deliberately and with malice aforethought announce routes either (a) using AS numbers which have not been issued to them by one of the five Regional Internet Registries and/or (b) covering IP address space that has not been formally issued to them, or to any of their legitimate customers by one of the five Regional Internet Registries? I guess that another way of expressing this question would be: Do RIPE contracts allow anyone to announce whatever the hell they want, willy nilly, and with no concern whatsoever for the formal allocation process? I wouldn't ask, but it appears that certain RIPE members do not feel particularly constrained to avoid announcing routes to IP address space that they are clearly and deliberately stealing from other parties. Is this the accepted norm in the RIPE region? Is such behavior it contractually permissible, within the RIPE region?

Fwd: Time to add 2002::/16 to bogon filters?
by Job Snijders 28 Jun '18

28 Jun '18

Dear working group, Feedback welcome - should 2002::/16 still be accepted in the DFZ? Kind regards. Job ---------- Forwarded message --------- From: Job Snijders <job(a)ntt.net> Date: Mon, 18 Jun 2018 at 23:08 Subject: Time to add 2002::/16 to bogon filters? To: NANOG [nanog(a)nanog.org] <nanog(a)nanog.org> Dear all, TL;DR: Perhaps it is time to add 2002::/16 to our EBGP bogon filters? It is kind of strange that in the default-free zone (where we don’t announce defaults to each other) - we will propagate what is effectively an IPv4 default-route, in the IPv6 DFZ. IETF has politely abandoned the prefix: https://tools.ietf.org/html/rfc7526 Wes George highlighted operational problems from accepting 2002::/16 on the data-plane slide 6: http://iepg.org/2018-03-18-ietf101/wes.pdf Is there still really any legit reason left to accept, or propagate, 2002::/16 on EBGP sessions in the DFZ? Kind regards, Job

New on RIPE Labs: Measuring the Adoption of RPKI Route Origin Validation
by Mirjam Kuehne 19 Jun '18

19 Jun '18

Dear colleagues, The number of Resource Certificates and ROAs is steadily growing, especially in the RIPE NCC service region. However, it remains unclear how widely BGP speakers on the Internet are actually using route origin validation (ROV) to drop or de-preference invalid announcements. In this new article on RIPE Labs, Andreas Reuter and his colleagues present their public monitoring platform - the ROV Deployment Monitor - and the methodology behind it. https://labs.ripe.net/Members/andreas_reuter/measuring-the-adoption-of-rpki… Kind regards, Mirjam Kühne RIPE NCC
