Our verdict on Driftnet
Driftnet is an internet-wide intelligence service for network defenders, security teams, and independent researchers. It supports reverse-searchable domain and IP registration data, with queries by name, organization, address, phone, domain, and email. The service also combines reverse WHOIS-style research with DNS records, certificate logs, internet-wide scans, fingerprints, geolocation, entity tagging, and vulnerability enrichment.
Free access is available for network administrators and independent researchers conducting non-commercial work. That access covers reverse-searchable registration data, historical and time-filtered queries, forward and reverse DNS, MX and TXT records, Certificate Transparency searches, port and protocol scans, and several enrichment options, including JARM, JA4X, JA4TScan, favicon, and vulnerability data. For buyers comparing tools, this makes Driftnet a broad research service rather than a narrowly focused registration lookup.
The web and API delivery model suits teams that need both interactive investigation and programmatic retrieval. The API supports domain and IP registration searches, filtering, time restrictions, on-demand IP and domain scans, and WHOIS collection. It can fit workflows that connect registration research with infrastructure discovery and certificate analysis. The main boundary is the free access policy: commercial users should not treat the free offering as their operating model. Driftnet is a strong fit for non-commercial OSINT-style research and defensive investigation, while teams seeking open-source software or a narrowly scoped WHOIS tool may prefer a more focused alternative.
