How Accurate Is IP Geolocation? What an IP Tracker Can and Can't Find

Type an IP address into any lookup tool and you'll get a dot on a map. It looks precise. It usually isn't. Here's what that dot really represents, how often it's right, and why no tool — however “highly accurate” it claims to be — can turn an IP address into a street address.

How IP geolocation works

An IP address has no location built in. Geolocation providers build databases that map address ranges to places by combining:

• Registry data — which organisation each block belongs to and the country it was registered in (the same records you see in an IP WHOIS lookup).
• ISP-published data — some providers publish geofeeds (RFC 8805) saying where each of their prefixes is used.
• Network measurement — latency from known points (light in fibre covers about 100 km per millisecond round-trip), traceroute paths and router names that contain city codes.
• Crowd-sourced signals — apps and websites that see the same IP alongside a GPS or postcode the user supplied.

The output is a best guess of where that range is used, plus an accuracy radius that most tools don't show you.

So how accurate is it?

Level	Typical accuracy	Notes
Country	95–99%	Wrong mostly for VPNs, satellite and some mobile networks.
Region / state	80–90%	Large ISPs sometimes register blocks at a national HQ.
City (within ~50 km)	50–80%	Better on fixed broadband in cities; much worse on mobile.
Postcode	Low	Often the centroid of a large area.
Street / house	Not possible	Only the ISP knows which subscriber had the IP.

Those figures are industry estimates and vary by country; providers themselves publish similar ranges. The key takeaway: treat the city as a hint, never as a fact.

Why the location is often wrong

• Mobile networks. Carriers route traffic through a few regional gateways, so a phone in one city often geolocates to another hundreds of kilometres away. Carrier-grade NAT means thousands of users share one IP.
• VPNs, proxies and Tor. The location is that of the exit server, by design.
• Corporate networks. Traffic may leave through the head office or a cloud security gateway in another country.
• Address reassignment. ISPs move blocks between regions, and databases lag behind by weeks or months.
• The “default point” problem. When a database only knows the country, it returns a point in the geographic middle. Famous cases saw a single farm in Kansas listed as the location of tens of millions of US IPs. That dot on the map is not a house.

Why Google seems to know more

Google's “approximate location” and similar features in other big services don't rely on IP alone. They blend it with nearby Wi-Fi networks, GPS from your phone, your location history and searches. When those signals are missing (a fresh browser, location permissions off), they fall back to the IP estimate — and become just as fuzzy as any lookup tool.

What about “exact location” IP trackers?

Tools and links that promise an exact location from an IP fall into two camps: ordinary geolocation lookups with confident-looking maps, or tracking links that ask the visitor's browser for its GPS position (which the visitor must approve). Neither turns an IP address into an address. The only route from IP to subscriber is through the ISP's records, which are released to law enforcement under legal process.

Try it on your own IP

Open the IP geolocation tool and compare the result to where you actually are. Then switch from Wi-Fi to mobile data and look again — the jump is often striking. If you use a VPN, check it isn't leaking your real IP through WebRTC or DNS.

An IP location is a statement about a network, not a person. It's excellent for “which country is this traffic from?” and unreliable for anything more precise.
