DNSviz currently always flags the root with a warning "./DNSKEY (alg 8, id 14748): No response was received until the UDP payload size was decreased, indicating that the server might be attempting to send a payload that exceeds the path maximum transmission unit (PMTU) size. (192.112.36.4, UDP_-_EDNS0_4096_D_KN)".
Testing G-root/192.112.36.4 with the RIPE Atlas probes, bit DO and bufsize=4096 shows no evidence of a problem (and the answer is well below 4096 bytes). It seems it affects only the path between G-root and DNSviz. Any idea? _______________________________________________ dns-operations mailing list [email protected] https://lists.dns-oarc.net/mailman/listinfo/dns-operations
