Errors (8)
  • . to ελ: 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. (78.104.145.227, 139.91.1.1, 139.91.191.3, 194.0.1.25, 194.0.4.10, 194.0.11.102, 2001:648:2c30::191:3, 2001:678:4::19, 2001:678:7::4:10, 2001:678:e:102::53, UDP_-_EDNS0_4096_D_KN, UDP_-_EDNS0_512_D_KN)
  • . to ελ: The DS RRset for the zone included algorithm 7 (RSASHA1NSEC3SHA1), but no DS RR matched a DNSKEY with algorithm 7 that signs the zone's DNSKEY RRset. See RFC 4035, Sec. 2.2, RFC 6840, Sec. 5.11.

Warnings (10)
  • . to ελ: The following NS name(s) were found in the authoritative NS RRset, but not in the delegation NS RRset (i.e., in the . zone): gr-m.ics.forth.gr See RFC 1034, Sec. 4.2.2.
  • ελ/DS (alg 7, id 55983): DNSSEC implementers are prohibited from implementing signing with DS algorithm 1 (SHA-1). See RFC 8624, Sec. 3.2.
  • ελ/DS (alg 7, id 55983): DNSSEC implementers are prohibited from implementing signing with DS algorithm 1 (SHA-1). See RFC 8624, Sec. 3.2.
  • ελ/DS (alg 7, id 55983): DS records with digest type 1 (SHA-1) are ignored when DS records with digest type 2 (SHA-256) exist in the same RRset. See RFC 4509, Sec. 3.
  • ελ/DS (alg 7, id 55983): DS records with digest type 1 (SHA-1) are ignored when DS records with digest type 2 (SHA-256) exist in the same RRset. See RFC 4509, Sec. 3.
  • ελ/SOA: 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. See RFC 6891, Sec. 6.2.6. (139.91.191.3, UDP_-_EDNS0_4096_D_KN)
