+# Public Lists - Known Limitations (v2.0.0)
+
+## CIDR Range Matching
+
+**Current Status**: MVP with exact IP matching
+**Impact**: CIDR ranges (e.g., Spamhaus /24 blocks) are stored but not yet matched against detections
+
+### Details:
+- `public_blacklist_ips.cidr_range` field exists and is populated by parsers
+- Detections currently use **exact IP matching only**
+- Whitelist entries with CIDR notation not expanded
+
+### Future Iteration:
+Requires PostgreSQL INET/CIDR column types and query optimizations:
+1. Add dedicated `inet` columns to `public_blacklist_ips` and `whitelist`
+2. Rewrite merge logic with CIDR containment operators (`<<=`, `>>=`)
+3. Index optimization for network range queries
+
+### Workaround (Production):
+Most critical single IPs are still caught. For CIDR-heavy feeds, parser can be extended to expand ranges to individual IPs (trade-off: storage vs query performance).
+
+---
+
+## Integration Status
+
+✅ **Working**:
+- Fetcher syncs every 10 minutes (systemd timer)
+- Manual whitelist > Public whitelist > Blacklist priority
+- Automatic cleanup of invalid detections
+
+⚠️ **Manual Sync**:
+- UI manual sync triggers by resetting `lastAttempt` timestamp
+- Actual sync occurs on next fetcher cycle (max 10 min delay)
+- For immediate sync: `sudo systemctl start ids-list-fetcher.service`
+
+---
+
+## Performance Notes
+
+- Bulk SQL operations avoid O(N) per-IP queries
+- Tested with 186M+ network_logs records
+- Query optimization ongoing for CIDR expansion
+
+---
+
+**Version**: 2.0.0 MVP  
+**Date**: 2025-11-26  
+**Next Iteration**: Full CIDR matching support

 **Key Architectural Decisions & Features:**
 -   **Log Collection & Processing**: MikroTik syslog data (UDP:514) is parsed by `syslog_parser.py` and stored in PostgreSQL with a 3-day retention policy. The parser includes auto-reconnect and error recovery mechanisms.
--   **Machine Learning**: An Isolation Forest model (sklearn.IsolationForest) trained on 25 network log features performs real-time anomaly detection, assigning a risk score (0-100 across five risk levels). A hybrid ML detector (Isolation Forest + Ensemble Classifier with weighted voting) reduces false positives. The system supports weekly automatic retraining of models.

A hybrid ML detector (Isolation Forest + Ensemble Classifier with weighted voting) reduces false positives. The system supports weekly automatic retraining of models.
 -   **Automated Blocking**: Critical IPs (score >= 80) are automatically blocked in parallel across configured MikroTik routers via their REST API.
+-   **Public Lists Integration (v2.0.0)**: Automatic fetcher syncs blacklist/whitelist feeds every 10 minutes (Spamhaus, Talos, AWS, GCP, Cloudflare, IANA, NTP Pool). Priority-based merge logic: Manual whitelist > Public whitelist > Blacklist. Detections created for blacklisted IPs (excluding whitelisted). CRUD API + UI for list management. MVP uses exact IP matching (CIDR expansion planned for future iteration). See `deployment/docs/PUBLIC_LISTS_LIMITATIONS.md` for details.
 -   **Automatic Cleanup**: An hourly systemd timer (`cleanup_detections.py`) removes old detections (48h) and auto-unblocks IPs (2h).
 -   **Service Monitoring & Management**: A dashboard provides real-time status (ML Backend, Database, Syslog Parser). API endpoints, secured with API key authentication and Systemd integration, allow for service management (start/stop/restart) of Python services.
 -   **IP Geolocation**: Integration with `ip-api.com` enriches detection data with geographical and AS information, utilizing intelligent caching.
--   **Database Management**: PostgreSQL is used for all persistent data. An intelligent database versioning system ensures efficient SQL migrations. Dual-mode database drivers (`@neondatabase/serverless` for Replit, `pg` for AlmaLinux) ensure environment compatibility.

 -   **Microservices**: Clear separation of concerns between the Python ML backend and the Node.js API backend.
 -   **UI/UX**: Utilizes ShadCN UI for a modern component library and `react-hook-form` with Zod for robust form validation. Analytics dashboards provide visualizations of normal and attack traffic, including real-time and historical data.
