Our main web site uses HTTPS certificates issued by comodo. So we have two CAA records like this:
@ CAA 0 issue "comodo.com"
www CAA 0 issue "comodo.com"
And we have multiple sub-domains with HTTPS certificates served by letsencrypt. Example CAA records like:
test1 CAA 0 issue "letsencrypt.org"
test2 CAA 0 issue "letsencrypt.org"
other CAA 0 issue "letsencrypt.org"
At the moment, when we have a new sub-domain, besides an A-record I also have to create a new CAA record. Can't I have a wild-card as sub-domain name, like this?
* CAA 0 issue "letsencrypt.org"
(I've tested this, but it doesn't work)
For the record: I'm not talking about wild-card domain certificates.
