Errors (8)
- edu to pitt.edu: 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. (130.49.127.11, 136.142.15.13, UDP_-_EDNS0_4096_D_KN)
- edu to pitt.edu: 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. (130.49.127.11, 136.142.15.13, UDP_-_EDNS0_4096_D_KN)
