  • gov to fdsys.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. (162.140.15.100, 162.140.254.200, UDP_-_EDNS0_4096_D_KN, UDP_-_EDNS0_512_D_KN)

  • fdsys.gov/DS (alg 8, id 41200): DNSSEC specification prohibits signing with DS records that use digest algorithm 1 (SHA-1).

  • fdsys.gov/DS (alg 8, id 41200): DS records with digest type 1 (SHA-1) are ignored when DS records with digest type 2 (SHA-256) exist in the same RRset.
