content: How precisely can websites track where (country/city/street) people visit the website? Hi! Let's say I start a website, "www.jumpingjacksrock.com", and I want to know which parts of the world my visitors come from. Would I be able to easily see on a mass level where my visitors come from? How precise is this? Do all websites track IP addresses and can therefore pinpoint their visitors' exact IRL address?  Finally and perhaps most importantly, does a system tracking the real-world location of all visitors on a mass scale have a name?
