Notices
Errors (24)
- . to tn: No valid RRSIGs made by a key corresponding to a DS RR were found covering the DNSKEY RRset, resulting in no secure entry point (SEP) into the zone. See RFC 4035, Sec. 2.2, RFC 6840, Sec. 5.11. (2001:43f8:120::25, TCP_-_NOEDNS_)
- . to tn: The DS RRset for the zone included algorithm 8 (RSASHA256), but no DS RR matched a DNSKEY with algorithm 8 that signs the zone's DNSKEY RRset. See RFC 4035, Sec. 2.2, RFC 6840, Sec. 5.11. (2001:43f8:120::25, TCP_-_NOEDNS_)
- tn zone: The server(s) responded over TCP with a malformed response or with an invalid RCODE. See RFC 1035, Sec. 4.1.1. (196.216.168.25)
- tn zone: The server(s) responded over UDP with a malformed response or with an invalid RCODE. See RFC 1035, Sec. 4.1.1. (196.216.168.25)
- tn zone: The server(s) were not responsive to queries over UDP. See RFC 1035, Sec. 4.2. (41.228.63.62, 2c0f:fab0:ffff:4:41:228:62:63)
- tn/DNSKEY (alg 8, id 36171): DNSSEC was effectively downgraded because the response had an invalid RCODE (SERVFAIL) with EDNS enabled. See RFC 6891, Sec. 7, RFC 2671, Sec. 5.3. (2001:43f8:120::25, TCP_-_NOEDNS_)
- tn/DNSKEY (alg 8, id 36171): The response had an invalid RCODE (SERVFAIL) until EDNS was disabled (however, this server appeared to respond legitimately to other queries with EDNS enabled). See RFC 6891, Sec. 6.2.6. (2001:43f8:120::25, UDP_-_EDNS0_4096_D_KN)
- tn/DNSKEY (alg 8, id 8629): DNSSEC was effectively downgraded because the response had an invalid RCODE (SERVFAIL) with EDNS enabled. See RFC 6891, Sec. 7, RFC 2671, Sec. 5.3. (2001:43f8:120::25, TCP_-_NOEDNS_)

- tn/NS: DNSSEC was effectively downgraded because no response was received from the server over UDP (tried 11 times) with EDNS enabled. See RFC 6891, Sec. 7, RFC 2671, Sec. 5.3. (2c0f:fab0:ffff:5:41:228:63:62, UDP_-_NOEDNS_)
