All major registries

RIPE, APNIC, LACNIC, AFRINIC, BGP routing data, and cloud provider self-published ranges.

GLEIF entity resolution

Clusters matched to Legal Entity Identifiers (LEIs) via the GLEIF golden-copy database of 3.3M registered entities.

REST API

JSON API for IP lookup, CIDR lookup, org search, bulk operations, and ASN queries. A free tier covers ordinary use; an API key is required to call it programmatically.

Free account, paid depth

Registering is free and unlocks an API key. Subscribing lifts the free tier's row caps on exports and full org/ASN listings.
