Usage and limits
Public network lookups use the canonical v1 JSON API with the existing input validation, timeout, response-size, rate, and SSRF controls. Tools using an API route transmit your input to this service. Browser-only tools are explicitly labelled.
API documentation: API reference. Canonical route: /api/v1/mac/.
