CAA (Certification Authority Authorization) records are a type of DNS record used by SSL certificates to indicate which certificate authorities can issue SSL/TLS certificates for your domain.
How to add CAA records
If your domain is pointing to Hostinger by nameservers, the required CAA records are added by default.
In case you need additional records - for example, to install a custom SSL, go to your DNS Zone Editor, scroll to the Manage DNS records area, and choose CAA on the type of record:
Which values to use?
Name
For your domain, insert @ as Name
For subdomains, insert the subdomain's name, eg. if you have a subdomain store.domain.tld, use store as name
Flag - the default value is 0. If you use 1, it can block the validation in case the tag is unknown by the Certificate Authority (CA)
Tag - you can choose from the following:
issue: The CA is authorized to provide a certificate for this domain
issuewild: the CA can issue wildcard certificates for this domain
iodef: URL that the CA can use to send an error message
CA domain - specify the Certificate Authority. Both the tag and the CA domain should be provided by your certificate issuer
TTL - the default value is 14400 seconds
In case your domain is pointing somewhere else by nameservers, you can add the default CAA records for Hostinger on your domain’s DNS Zone using the following values:
Name | Content | TTL |
@ or subdomain | 0 issue digicert.com | 1440 or default |
@ or subdomain | 0 issuewild digicert.com | 1440 or default |
@ or subdomain | 0 issue sectigo.com | 1440 or default |
@ or subdomain | 0 issuewild sectigo.com | 1440 or default |
@ or subdomain | 0 issue letsencrypt.org | 1440 or default |
@ or subdomain | 0 issuewild letsencrypt.org | 1440 or default |
@ or subdomain | 0 issue globalsign.com | 1440 or default |
@ or subdomain | 0 issuewild globalsign.com | 1440 or default |
@ or subdomain | 0 issue comodoca.com | 1440 or default |
@ or subdomain | 0 issuewild comodoca.com | 1440 or default |
NOTE
If you use Cloudflare, set the Proxy status to DNS only for all CAA records
How to Edit or Delete CAA Records
It is recommended to keep all the default CAA records and not delete them, as it can prevent the SSL to install successfully. To edit or delete a CAA record:
For domains pointing to Hostinger by NS records - check this article: How to Manage DNS Records at Hostinger
If your domain is pointing elsewhere by NS records, go to your domain's DNS Zone management on the provider you pointed the domain to and manage them from there
After applying any changes to your DNS zone, consider up to 24 hours to fully propagate.
