I was reviewing my Analytics for the past year and noticed a couple dozen different IP addresses showing up as referrals. I tracked a few of them down to be Google (why are Google IP addresses coming in as referrals?), but there are still quite a handful that come from "private" IP addresses:
10.x.x.x range of IP addresses, they are all using Port
15871 which I found interesting. I have the company IP address blocked from Analytics, so it shouldn't be any internal visits. Any clue what's going on here?
