Technical notes
Constraints
- MAC addresses are more stable than IPs but randomized addresses can break continuity.
- Ping, ARP, hostname, and vendor signals are all best-effort.
- Observed inventory remains local; public screenshots use synthetic data.
- Designed only for networks the operator owns or may inspect.

- Filtering, search, scan history, and scheduled scans.
