Errors (3)
  • NSEC3 proving non-existence of itu.int/DS: An iterations count of 0 must be used in NSEC3 records to alleviate computational burdens. See RFC 9276, Sec. 3.1.
  • NSEC3 proving non-existence of itu.int/DS: An iterations count of 0 must be used in NSEC3 records to alleviate computational burdens. See RFC 9276, Sec. 3.1.
  • itu.int/DS has errors; select the "Denial of existence" DNSSEC option to see them.
Warnings (12)
