14:03 < Xavier_RIPENCC> Bart Braem, has begun the presentation "An Introduction to Community Networks".
14:08 < maha> hi, does anybody know if the "Cross-registry Authentication for IRR Data" BOF will be recorded this evening?
14:09 < Suzanne_RIPENCC> Hi maha, BoFs are not recorded.
14:10 < maha> thx
14:18 < ripe393> Hello Dear Colleagues,
14:21 < Xavier_RIPENCC> Jim Cowie has begun the presentation "Change of Address: Issues in the IPv4 Transfer Market"
14:39 < Xavier_RIPENCC> Jim Cowie has asked for questions.
14:42 < shane> I thought RPKI stuff was only source validation, not path validation?
14:43 < AlexBand> shane it is... path validation is being developed in the IETF now
14:44 < shane> Right, so RPKI won't solve hijacking, as it is straightforward to play games with AS paths. It will make it slightly harder, and at least avoid misconfigurations. (Or more likely, trade one kind of misconfiguration for another...)
14:45 < AlexBand> it'll solve most fat fingering now, which arguably is the most common problem
14:45 < robert_ripencc> it's very good at preventing fat fingering
14:45 < robert_ripencc> 🙂
14:45 < AlexBand> 😛
14:45 < robert_ripencc> but indeed, path validation is the next step
14:45 < ripe504> in the ARIN region, when some /8's transferred space, the reverse DNS was changed so the old /8 reverse domain no longer held the /8 reverse domain and new delegations to the proper /16s were entered.
14:46 < ripe504> ok, so better said as "old /8 holder no longer held the /8 reverse domain"
14:46 < robert_ripencc> that's neat
14:47 < dfk> quarantine coimg back!
14:48 < ripe504> seems that is the only way to do it so new holder of more specific does not have to depend on old holder of /8 to provide reverse domain name service.
14:53 < Xavier_RIPENCC> Bendert Zevenbergen, has begun the presentation " Internet Engineering Meets Philosophy: Establishing Ethical Guidelines for Networked Systems Research
14:58 < shane> Hm. I would sure be happy to know that my ISP was following the correct process, even if that didn't fix my Internet connection. 😛
15:09 < shane> Speaking to fellow engineers makes sense.
15:09 < shane> But we can all predict what lawyers will say.
15:09 < shane> "Don't do it."
15:09 < shane> And also, "you need more lawyers". 😉
15:11 < brian-1213> shane: You're such a cynic.
15:11 < ripe393> it's very good
15:12 < jelte> i tell that joke to every lawyer i meet to filter the good ones from the bad by their reaction
15:12 < jelte> or joke, that observation :p
15:12 < robert_ripencc> i hear some people predict the future from used coffee
15:13 < jelte> granted, it's also what sysadmins tend to say to requests from users 😉
15:14 < teun-12859> my future sure has coffee in it
15:16 < Xavier_RIPENCC> Bendert Zevenbergen has asked for questions.
15:19 < dfk> don't insult the audience unnecessarily!
15:21 < dfk> there is streetview in de!
