Quad9 achemine vos requêtes DNS à travers un réseau sécurisé de serveurs dans le monde entier. Le système utilise les renseignements sur les menaces provenant de plus d’ une douzaine de sociétés de cybersécurité parmi les plus importantes de l’ industrie pour donner une perspective en temps réel sur les sites Web sécuritaires et sur les sites connus pour contenir des logiciels malveillants ou d’ autres menaces. Si le système détecte que le site que vous voulez atteindre est connu pour être infecté, vous serez automatiquement bloqué d’ entrée - gardant vos données et votre ordinateur en sécurité.< / p >

la gestion des ancres de confiance. Gestion externe de l'ancrage de la confiance,
par exemple avec une ancre non liée, n'est plus nécessaire
et n'est plus recommandé.

Ancres de confiance déjà installées, à l'emplacement par défaut -

- seront préférés et utilisés pour la validation DNSSEC, cependant
getdns se repliera sur les ancres de confiance obtenues par l'intermédiaire de l'interface intégrée.

Pour éviter que les ancrages de confiance DNSSEC expirés ne soient utilisés pour
