The literal root .xn--czro89b is not in the current IANA delegation list
The literal root .xn--czro89b is not in the current IANA delegation list. The comparison may still show observed renewal or transfer information for existing names.

Review the registry DNSSEC fields and the chosen registrar’s documented DNSSEC feature. The available data does not establish an individual-domain DNSSEC workflow for .商標.
