Domain Control Validation (DCV) — SSL/TLSBefore a Certificate Authority will issue a certificate for a domain, the requestor must prove they have control over that domain. This process is known as domain control validation (DCV).
Who needs to perform DCV
If your application is on a partial/CNAME DNS setup — meaning that someone else runs your authoritative nameservers — you may need to perform DCV.
Performing DCV gives you more control over the valdiation method, as well as ensuring that your application does not experience any downtime.
If your domain is on a full setup
, Cloudflare handles DCV automatically on your behalf using a TXT record. For more details, refer to Enabling Universal SSL
If your domain is using a custom certificate
, you need to handle DCV on your own when you obtain certificates from a CA.
