IP Geolocation — Where an Address Is, and Who Announces It
This reports what is known about an address: approximate geographic location, the organisation it is allocated to, and the autonomous system announcing it. Accuracy varies enormously — country level is usually reliable, city level often is not, and addresses behind a large provider or a VPN may resolve nowhere near the user.
Why run it
For an operator the network and autonomous system fields matter more than the map pin. Identifying that a burst of traffic originates from a single hosting provider's network tells you something actionable; knowing it is nominally in a particular city does not. It is also how you interpret a latency complaint — a user reporting slowness from a region your delivery is not optimised for is a different problem from one nearby, and the address is often the only clue you have.
Why automate it
The useful application is aggregate rather than individual. Where your traffic actually comes from, in networks and regions rather than in assumptions, is a question that answers itself when you enrich traffic logs continuously — and it frequently contradicts what everyone believes. That distribution is what should drive delivery decisions. Doing it per-address by hand answers a question about one visitor; doing it continuously answers a question about your service.
What it gives you
Context for an address that is otherwise just a number, with the network and operator detail that is genuinely actionable. Aggregated over real traffic it tells you where your users are rather than where you assumed.
