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
