Ip Address To Company Identification

via “ip-address-to-company-identification”

Real-time company and person data enrichment API.

Unique: Clearbit's IP intelligence uses a proprietary database of corporate IP ranges combined with ASN (Autonomous System Number) mapping and reverse DNS lookups to identify companies from visitor IPs, with JavaScript-based client-side collection to avoid server-side IP logging and improve privacy compliance.

vs others: More accurate company identification from IP addresses than Clearbit's direct competitors due to continuous IP range database updates and integration with multiple ISP/ASN data sources, though less effective than first-party intent data platforms (6sense, Demandbase) for detecting buying intent signals.

via “ip-address-geolocation-and-company-inference”

** - Lead enrichment and data intelligence platform.

Unique: Combines IP-to-ASN mapping with Clearbit's company database to infer corporate ownership of IP blocks, enabling company-level visitor identification without third-party tracking; includes privacy-safe fallback to geolocation-only data for non-corporate IPs

vs others: More privacy-compliant than cookie-based visitor tracking because it uses only IP metadata; more accurate than MaxMind or IP2Location for company inference because it cross-references against Clearbit's 50M+ company database
