Well, if there are doubts whether https://de/ points to a A/CNAME record in the .de top-level domain or resolves to a local server (by DNS adding search suffix) and is therefore treated as equivalent to https://de.example.test/ then the TLS standard should say something about this. Also matching rules for dNSName are affected. > It should be more the policy of the CA that should either refuse to > issue such certificates, or require a written agreement that they are > intended only for intranet use. Nelson was asking for adding an additional provision to Mozilla's policy.
