Errors (7)
  • nl/DS (alg 13, id 17153): DNSSEC was effectively downgraded because no response was received from the server over UDP (tried 10 times) with the DO bit set. See RFC 4035, Sec. 3.2.1. (192.33.4.12, UDP_-_EDNS0_4096_)
  • nl/DS (alg 13, id 17153): DNSSEC was effectively downgraded because no response was received from the server over UDP (tried 10 times) with the DO bit set. See RFC 4035, Sec. 3.2.1. (192.33.4.12, UDP_-_EDNS0_4096_)
  • nl/DS (alg 13, id 17153): No response was received from the server over UDP (tried 10 times) until the DO EDNS flag was cleared (however, this server appeared to respond legitimately to other queries with the DO EDNS flag set). See RFC 6891, Sec. 6.1.4. (192.33.4.12, UDP_-_EDNS0_4096_D_KN)

Warnings (2)
  • ./DNSKEY (alg 8, id 20326): 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. (192.33.4.12, UDP_-_EDNS0_4096_D_KN)
