How Accurate Is IP-Based Geolocation, Really?

An IP address doesn't carry a GPS coordinate

Unlike a phone's GPS, an IP address itself contains no location data at all — it's just a numeric identifier assigned by an internet service provider. Looking up "where an IP is" actually means looking up which organization was assigned that block of IP addresses, and inferring a location from that.

Why the result is usually a city or region, not an address

Internet service providers typically assign IP address ranges to a regional point of presence, not to an individual customer's exact address. IP geolocation databases map that assignment to an approximate location — often accurate to the city or region level, but essentially never precise enough to pinpoint an exact street address.

Where it gets noticeably less accurate

A VPN or proxy makes a lookup report the location of the VPN server, not the actual user. Mobile carrier networks often route traffic through a small number of centralized points, so a phone's IP can appear to be located in a completely different city than the phone actually is. Corporate networks routing traffic through a central office show that office's location for every employee, regardless of where they're actually working from.

Try it yourself

Our IP Lookup tool shows your own public IP's approximate location, or looks up any IP you enter, using a public IP-geolocation service called directly from your browser.
