In all cases, the validation must have been initiated within the time period specified in the relevant requirement (such as Section 4.2.1 of this document) prior to Certificate issuance. For purposes of IP Address validation, the term Applicant includes the Applicant's Parent Company, Subsidiary Company, or Affiliate.

CAs are not required to verify IP Addresses listed in Subordinate CA Certificates via iPAddress in excludedSubtrees in the Name Constraints extension prior to inclusion in the Subordinate CA Certificate.
