  • gov to ecfr.gov: 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. (173.245.58.88, 173.245.59.84, 2606:4700:50::adf5:3a58, 2606:4700:58::adf5:3b54, UDP_-_EDNS0_4096_D_K, UDP_-_EDNS0_512_D_K)
  • gov to ecfr.gov: 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. (173.245.58.88, 173.245.59.84, 2606:4700:50::adf5:3a58, 2606:4700:58::adf5:3b54, UDP_-_EDNS0_4096_D_K, UDP_-_EDNS0_512_D_K)
