Domain validation behavior for DV certificates
DV certificate validation differs from OV and EV validation in several important ways.
No validation reuse
Each DV certificate order requires domain validation. Previously validated domains cannot be reused and validation must be completed for every new order, renewal, and reissue.
No prevalidation
Domain prevalidation is not supported for DV certificates. Validation must be completed as part of the order process.
Single DCV method per order
With DV certificate orders, you must use one DCV method to validate all domains on the order.
Method restrictions
The following DCV methods are not supported for DV certificates:
HTTP Practical Demonstration with unique filename
ACME HTTP-01 for IP address validation
No IP address validation via ACME
If the certificate includes an IP address, you must use HTTP Practical Demonstration to validate it. If the certificate includes a wildcard domain, you cannot use HTTP Practical Demonstration to validate it. DigiCert recommends that you do not include wildcard domains and IP addresses on the same DV certificate.
