Clocks, phone numbers, IP addresses, etc. can be associated with locations in VTI, and those locations with related punches. The location County Clerk might be associated with a clock, and the location City Hall associated with an IP address. At first glance in Who Is In you might just see the location name associated with the punch, but if you hover your cursor over that location a pop-up will display that will tell you the source of a punch, in many cases. For example, it might say “From Web Punch” and include the IP address, or it could say “From DCD” which means it came from a clock (i.e., a Data Collection Device).
