Walkthrough

The changes update the LocalAccessMiddleware to expand local IP detection coverage. An additional IP address is added to the allowlist, and the detection logic now treats IPs starting with "192" as local and includes explicit handling for the 172.16.0.0/12 private range with safe parsing.

Changes

Cohort / File(s)	Summary
Local IP Detection Expansion middleware/local_access.py	Added "192.168.0.100" to ALLOWED_LOCAL_IPS. Broadened local IP detection to cover 192.x.x.x range and 172.16–31.x.x private range with safe octet parsing and try/except error handling.

Estimated code review effort

🎯 2 (Simple) | ⏱️ ~12 minutes

• Verify that IP range detection logic correctly identifies 192.x.x.x and 172.16–31.x.x ranges
• Confirm safe parsing handles malformed IPs without exceptions
• Validate that the added allowlist entry "192.168.0.100" is intentional and appropriate for the deployment environment

Poem

🐰 Hops through networks, checking each address,
192 and 172 now pass the test,
Safe parsing guards from crashes and mess,
Local access flows with greater finesse! 🌐✨
