Global Edge dedicated certificates support only DNS 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 does not support changes to DNS records. Check with your domain name registrar, agency, or your own DNS management system to see how to make changes in advance. - For domains registered with [Global DNS](https://www.ncloud.com/product/networking/globalDns) on NAVER Cloud Platform, you can change CNAME records using Global DNS. ## DNS validation method After the certificate application is completed, validation values will be generated for each domain's CNAME record name and record value. To validate DNS: 1. Go to **Cloud Certificate** > **Certificate List** > **Certificate details** to check the DNS validation value for your domain. It appears in the following format: | Record Name | Record Type | Record Value | | --- | --- | --- | | _acme-challenge.mydomain1.example.com. | CNAME | Generated token value | - **Record Name**: The validation value to enter as the DNS record name. - **Record Type**: Set the record type to **CNAME** in the DNS management system. - **Record Value**: The validation value to enter as the DNS record value. 2. Enter the DNS validation value through your domain's DNS management system. - Domains that successfully complete DNS validation will have their validation status change from **In progress** to **Succeeded**. Note The certificate is issued after all domains included in the certificate have been successfully validated. Go to **Cloud Certificate** > **Certificate List** > **Certificate details** to check the validation status of your domains.
