Hi all, After my presentation this week on Dubai about this topic, I got several folks telling me that they believe this is very interesting. Here is again the link to the document: https://tools.ietf.org/html/draft-palet-ietf-v6ops-he-reporting-00 And to the slides from this week: https://ripe75.ripe.net/presentations/129-ipv6-hev2-v2.pdf The major concern is privacy issues. My response to that is that we have the same when we log other protocols, including CGN, etc., in addition to that, for signaling the ISP that there is a problem, we don’t really need to log the complete source IPv6 address that doesn’t work, just the prefix, and also, we have a simpler alternative. If the logging is only for the destination IPv6 address and not the source one, I think in a big % of the cases, is sufficient for the ISP to know that there is some problem from its network to the failed destination (so the ISP could replicate the failure from any other source address in its network to the same destination). This logic, I believe, will only fail if the problem is specific to the “interior” of the customer network, which will be out of the scope of the ISP (and even do, the ISP will be able to tell the user --- hey this destination works from my network, not from yours, so something got broken inside your network). I’m going to submit a new version of this document on Sunday, so if you have inputs, please, let me know ASAP. Thanks in advance for your inputs !
