DNS01 _acme-challenge subdomain


when i create a subdomain for my domain “example.com” for validation like

_acme-challenge IN NS my.external.dns.com

Is it then possible to create create certficates for any hosts in example.com ?

As implemented by Let’s Encrypt, _acme-challenge.example.com may be used to validate the name example.com and the wildcard *.example.com.

To validate foo.example.com or *.foo.example.com, you would use _acme-challenge.foo.example.com.


Thanks, i wasn’t sure and testing with our DNS hoster would have taken me several days :slight_smile:
