Hi Riz -- what does the IP match log tell you? It shows the same three people accessing the same site at about the same time on three different days. But, each day, it shows the same IP address for each of the three people (but a different IP on each of the different days).

I thought each user would have a unique IP, but that the IP would stay consistent for each individual from day to day (as long as they were using the same device in the same location).

Clearly, I have no idea what an IP address actually is or shows!!!
