This is Response Rate Limiting in action… they’re not explicitly limiting NXDOMAIN responses; they’re limiting identical responses. If Bert’s server was asking for the same A record over and over that would get truncated and forced over to TCP as well. It’s probably not only F, although I don’t think I’ve seen a comprehensive list of which root instances are running RRL. _______________________________________________ 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
