- Nouveau endpoint API GET /api/entities/subnet/:subnet - Utilise view_dashboard_entities (données agrégées) - Retourne stats globales + liste détaillée des IPs - Filtre par les 3 premiers octets du subnet - Nouveau composant frontend SubnetInvestigation.tsx - Affiche toutes les IPs d'un subnet /24 - Tableau avec: IP, détections, JA4, UA, pays, ASN, menace, score - Boutons 'Investiguer' et 'Détails' par IP - URL simplifiée: /entities/subnet/x.x.x.x_24 (_ au lieu de /) - Évite les problèmes d'encodage URL - Conversion automatique _ → / côté frontend - Correction route ordering dans App.tsx - /entities/subnet/:subnet avant /entities/:type/:value - Routes backend réordonnées - /api/entities/subnet/:subnet avant les routes génériques Testé avec 141.98.11.0/24 → 6 IPs trouvées, 1677 détections Co-authored-by: Qwen-Coder <qwen-coder@alibabacloud.com>
