# Local IP Databases

These files are downloaded from sapics/ip-location-db GitHub Releases.

- `dbip-city-ipv4.mmdb` and `dbip-city-ipv6.mmdb`: DB-IP Lite city data, CC BY 4.0.
- `origin-asn.mmdb`: origin ASN data, PDDL.

Refresh them with:

```bash
scripts/download-geoip-mmdb.sh
```

The Rust backend loads these local MMDB files on startup and does not call a third-party IP lookup API.
