Even they only guess based on what they can find out about who controls which block, and yes they're careful with anything they have that isn't public because they sell use of it. All geo-ip databases will get my home static IP in the right country (courtesy of RIPE) but most have the wrong county let alone city, one or two will put me in the nearest city (about half an hour drive away) revealing fairly detailed knowledge of my ISPs network infrastructure. In regions near national borders it is very common for the IPs to be recorded in the wrong country because fundamentally IP addresses follow network boundaries not geographic ones. My ISP has the exact address but it takes a human being looking at two separate screens (billing and provisioning) to put them together. I've been on the end of a support call when someone did just that to verify that I still had the static IP after a change. GDPR prevents them from passing on that level of detail or doing anything with it other than routing packets down the right bit of fibre. -- Steve O'Hara-Smith <steve@sohara.org>
