  • cz to rhybar.cz: 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. (217.31.204.70, 217.31.204.71, 2001:1488:800:400::2:70, 2001:1488:800:400::2:71, UDP_-_EDNS0_4096_D_KN, UDP_-_EDNS0_512_D_KN)
