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.
