DNS validation

Available in Classic and VPC

Before issuing a certificate, ownership for all domains you apply for must be validated. You can choose one of two ways to validate domain ownership: DNS validation or Email validation.

DNS validation prerequisites

To perform DNS validation when validating domain ownership, you need permission to change the CNAME record in the domain's DNS.

• Certificate Manager doesn't provide DNS record changes. Check with your domain name registrar, agency, or your own DNS management system to see how to make changes in advance.
• Domains registered in the Global DNS service of NAVER Cloud Platform can change their CNAME records using Global DNS.

DNS validation method

When you select DNS validation as the validation method when applying for a certificate, it generates a CNAME record name for each domain and a validation value to be entered in the record value after the application is complete.

You can validate DNS as follows.

1. Go to Certificate List > Certificate Details to see the DNS validation value for your domains. It appears in the following format.

• Record Name: it is a validation value that is entered in the DNS record name.
• Record Type: when set up in the DNS management system, the record type must be CNAME.
• Record Value: it is a validation value that is entered in the DNS record value.

2. Enter the DNS validation value through your domain's DNS management system. Wildcard (*) domains will have a validation value generated in the corresponding places.
   • Domains that successfully complete DNS validation will have their validation status change from In Progress to Successful.
