If you use a hosted DNS service, please refer to this article .
Pre-requirement:
You must know which syntax to use when configuring your DNS zone file. This depends on your DNS. Please see the table below to determine the syntax type to use when configuring your CAA record. Or, for a complete guide to adding a CAA record, please select the link relating to your DNS.
| Syntax Type | DNS Product |
| Standard BIND |
BIND 9.9.6 and higher
PowerDNS 4.0.0 and higher NSD 4.0.1 and higher Knot DNS 2.2.0 and higher Simple DNS Plus 6 Windows Server 2016 |
| Legacy BIND |
Any version prior to BIND 9.9.6

| Generic | Google Cloud DNS |
General How-To: Adding Entrust to your CAA record
1. Open your domain's DNS zone file in Notepad. (Note that how you access your DNS records depends on where your domain is registered.
If you are using a hosted DNS service please see our technote on how to access your DNS record here.
)
2. You will have to configure the file to determine the CA(s) you wish to include your CAA record. Note that only adding one CA will limit issuance of SSL/TLS certificates on that domain to just that CA. Also note that domains may have more than one CA listed in a CAA record.
In order to add Entrust to your CAA record, add the below to your DNS zone file (please be sure to select the correct syntax):
*using "example.com" as the domain name
| Standard BIND Zone File |
| example.com. CAA 0 issue "entrust.net" |
| Legacy BIND Zone File |
| example.com. TYPE257 \# 18 00056973737565656E74727573742E6E6574 |
| Generic |
| 0 issue "entrust.net" |
This CAA record will indicate that Entrust is the authorized CA for domain.com and all subdomains. If a subdomain requires a different authorized CA, then a CAA record can be created separately for that subdomain.
3. Save your zone file and exit Notepad.
