NS or CAA record setup

  • Record name: This is the record name assigned for your NS or CAA record (e.g. NS record:; or CAA record:

If you're configuring for a  root domain, enter '@' or leave blank (this may vary depending on the DNS provider, please double before proceeding, e.g. enter @ before

In the case of a subdomain, enter only the subdomain (e.g. if the domain is, then enter before

  • Content: During the NS/CAA setup process, you need to input the value of the record (NS record:; or CAA record: 0 issue "").

For CAA, the content has 3 fields:
flag: 0 (non-critical) or 1 (critical);
tag: issue/issuewild/iodef ; and
tag value: the certificate authority who will issue a digital certificate, e.g. “”.
