The optical fiber cable that supplies a business is used for clients and staff.
The business has an online enquiry form for bookings on its web page. It also provides free WiFi access to clients and staff via a router in the main office. A password is required but is not specific to any user. In other words one password gives anyone access.
If a person using this WiFi connection in the office accesses the public web page of the company and submits an enquiry through the reservations enquiry form, can the actual computer used be traced back, whether from the online enquiry form or any other way without having access the "offending" computer.
No IP cloaking was used. There are five company computers permanent connected and powered on 24/7 which are also connected to the WiFi. The enquiry could have easily come from one of them.
