I'm really sorry, but I'm actually having trouble contextualizing the failure mode that you are talking about here. Didn't I agree with you in a previous message that we should try all the upstream DNS servers? > You may be right that hacking up a working prototype isn't that hard. > But the failure modes change from "the internet is down" or may "I > cannot access site A", to "site A is working every third attempt, except > it is entirely broken on device X" maybe even with an added "ah, but > it works on device X if I go into the kitchen". Didn't we agree that we aren't round-robining? > Hmm, while writing this is occurred to me that it might make sense to > just export the ISP DNS server(s) directly in the MPvD-only RAs? This would certainly work, but now you can't have your nice local resolver that does what you want. However, I think you are right that this is the right default behavior for MPvD-aware devices.
