## API quick reference

- Plain-text IP: `curl ip.sb` (or https://api.ip.sb/ip)
- IPv4 only: `curl ipv4.ip.sb`
- IPv6 only: `curl ipv6.ip.sb`
- Geolocation JSON: https://api.ip.sb/geoip (optionally /geoip/8.8.8.8)

## Data sources

Geolocation comes from MaxMind GeoIP and IPinfo databases (updated
daily, queried locally). Whois/RDAP data comes from the responsible
registries and registrars. Geolocation corrections go to MaxMind, not
to IP.SB.
