This will still break things because prior to the change, large authoritative ANY responses are truncated without setting TC=1. After the change, large ANY responses enter the cache and trigger TC=1 responses to stub resolvers (recursors do not silently truncate ANY responses, it seems), which may not be prepared to accept such large responses (or even fall back to TCP). Some breakage is unavoidable. Considering that ANY queries rarely give the results expected by the sender, refusing them outright makes sense to me. _______________________________________________ dns-operations mailing list [email protected] https://lists.dns-oarc.net/mailman/listinfo/dns-operations dns-jobs mailing list https://lists.dns-oarc.net/mailman/listinfo/dns-jobs
