Why does someone else's personalized signature on some websites show my geographical location?
According to the results of IP display, it can help to refer to your geographical location, but sometimes this thing is not accurate. For example, you are in Beijing, but your Internet service provider is far away in Tianjin. At this point, your geographical location displayed in the forum is Tianjin. It's not accurate, but it can be used as a reference. At least the target is near there.
