But, unless the resolver is v6-only, it does not prevent DNS resolution (otherwise, no .net name would work). So, it is probably not the reason why your customer has problems. A test with the RIPE Atlas probes, to show that a few of them have the problem: % blaeu-resolve --nameserver 2001:502:1ca1::30 -r 100 --dnssec -q DS sportsproducts.net Nameserver 2001:502:1ca1::30 [] : 96 occurrences [TIMEOUT] : 3 occurrences Test #25636763 done at 2020-06-05T11:20:54Z _______________________________________________ dns-operations mailing list dns-operations@lists.dns-oarc.net https://lists.dns-oarc.net/mailman/listinfo/dns-operations
