https://190.212.72.34.bc.googleusercontent.com にアクセスしようと
証明書を作ろうとしましたが、CAAで作れませんでした

$ sudo certbot certonly --standalone --register-unsafely-without-email --agree-tos --non-interactive -d 190.212.72.34.bc.googleusercontent.com

IMPORTANT NOTES:
 - The following errors were reported by the server:

   Domain: 190.212.72.34.bc.googleusercontent.com
   Type:   caa
   Detail: CAA record for 190.212.72.34.bc.googleusercontent.com
   prevents issuance

原因

CAAレコードをみるとpki.googしかなく、letsencrypt.orgは認証局として証明書の作成を許可されていませんでした。

まとめ

*.bc.googleusercontent.comは使えないので、別でドメインを取得するしかないようです
