Map a company's IP footprint
Every netblock we can evidence, with the source and confidence behind each one — resolved from registry, BGP, RPKI, and GLEIF legal-entity data. Works the other way too: look up any IP and get its registered holder, or the carrier announcing it, labelled as such.
Company footprints, with provenance
A company's address space is scattered across hundreds of registry names and sub-allocations. We cluster them back together and tie the result to GLEIF Legal Entity Identifiers — subsidiaries, corporate parents, and jurisdictions included — with the evidence source and confidence tier shown for every range.
Customer & hosting relationships
See which enterprises run inside an ISP's network, and which providers a company's own infrastructure actually depends on — decoded from sub-allocations, containment, and RPKI authorizations that WHOIS alone can't surface.
Change tracking
The index is rebuilt weekly from primary sources — what changed shows new entrants, growth, and shrinkage across the largest networks on the internet.
REST API & exports
JSON API for IP, CIDR, org, ASN, and bulk queries — free with an API key. Subscribing lifts the row caps on CSV exports and full listings. Data from RIPE, APNIC, LACNIC, AFRINIC, ARIN, BGP (via CAIDA), RPKI, IRR route objects, PeeringDB, and GLEIF — full provenance on the data licence page.
