Hi, I wondered a while whether this would be more appropriate to post here or as an issue in ISC's gitlab, but came to the conclusion that for now the best place would be here. The reason is that the "how to reproduce the problem" bit is quite fuzzy. If someone from ISC wants this reported as a

Thanks to those who replied to my earlier email. I've straightened out my routing issues but I'm still having name resolution failures. Since then I've upgraded to OpenBSD 7.6 with BIND 9.20.2 from packages, with no change. I'm getting frequent lookup failures on most

Are you running NTP? (e.g. is your time correct on the device running bind?) Forwarding to another recursive resolver or using hints? I'm running Bind 9.18.29 on FreeBSD 14.1-p4 on a RPI4. No jails. (It runs on RPI5 also) I also have it setup to run unbound 1.21.0 for comparison. (BTW, that works

Hi Steven. As you said, `listen-on {...;};` tells BIND which addresses to register for incoming traffic. This can be a list, not just one address. Any query received on (say) 10.0.0.1 will be responded to from the same address. It is possible to choose which address to use for outgoing queries/fet

Hi, I'm running BIND 9.18.29 on OpenBSD 7.5, installed from ports. It does recursion and resolving for a small home network. Multiple times a day, clients will make a DNS request that fails. The web browser will say it can't find the address (DNS lookup failure). Hitting retry a couple of ti

named is looking for K files that match the DNSKEY records in the zone and is not finding them. Removing K files too early or having them in the wrong place will produce these errors. You can work out which DNSKEY record matches the number with dig +rrcomments or dig +multiline. [beetle:~/git/bi
