## AI overview

This French article explains a new RFC that standardizes an RDAP extension for retrieving DNS TTL values associated with registered domain and name-server objects. It describes the JSON response property, clarifies that the value is the registry-recorded TTL rather than the resolver's remaining cache time, and notes support in several RDAP libraries.

## Source excerpt

Puisque le RFC 9803 étend le protocole d'avitaillement EPP pour ajouter des TTL spécifiques aux noms de domaine enregistrés, il était logique que le protocole d'interrogation RDAP permette d'obtenir cette information. C'est ce que permet l'extension normalisée dans ce nouveau RFC.
