Prefix lookup
Enter an IPv4 address or a /24 prefix to see its published attributes for the
2026-07 release — geolocation, ASN, ownership, registry and risk signals.
Everything is read directly from the monthly Parquet data in your browser; nothing is sent to a server.
Granularity is one record per /24 block. A full IP is resolved to its containing
/24. Unrouted or unallocated space returns no record. Data source:
the current monthly release.
