Website Visitor Identification

Most B2B website traffic never fills out a form, and most of that traffic represents real companies with a real reason for being on the site. Reverse-IP identification tools match a visitor's IP address against a database of known corporate IP ranges to surface the company name — not the individual — behind an anonymous visit.

What the technique actually tells you, and its real limits

It tells you       a company, with reasonable confidence for
                   businesses on a static corporate IP range
It does NOT tell you the individual visitor's identity or role
                   — this is a genuine, structural limitation, not
                   an implementation gap
It's unreliable for remote workers on home broadband, mobile
                   networks, VPNs and most small businesses on
                   consumer ISPs

Company-level identification, not person-level, is the accurate framing — anything sold as identifying the individual visitor by name is either using a different, more invasive technique (which raises its own separate consent and compliance questions) or overstating what reverse-IP matching does. Set expectations accordingly before building a process around the data.
