An IP address is like a digital return address for devices connected to the internet. Every time you open a website, send a message, or stream a video, your IP address communicates with servers to deliver data to your device.
Many people wonder: How accurate is IP geolocation? Can an IP address reveal someone's exact street address or identity? This guide breaks down how IP location lookups work and what they can actually tell you.
When you check an IP address using an online lookup tool, the query searches global IP registration databases (such as RIPE, ARIN, APNIC) and commercial geolocation databases.
99%+ accuracy for determining the country and region of connection.
Approximate city location based on the ISP routing station or node.
Identifies the Internet Service Provider (e.g., Reliance Jio, Airtel, Comcast).
Broad postal zone associated with the regional internet registry center.
| Location Level | Accuracy Rate | Notes |
|---|---|---|
| Country | 99% - 100% | Nearly always accurate unless a VPN or proxy is used. |
| State / Region | 80% - 90% | Accurate for most major telecom providers. |
| City | 50% - 80% | Points to the nearest ISP hub, which may be miles away. |
| Street / House | 0% | Impossible via public IP lookups due to privacy protection. |
If you check your own IP address and see a neighboring city instead of your exact location, here is why:
IP geolocation is not based on GPS or satellite signals. Instead, it relies on databases built by tracking which internet service providers were allocated specific IP address ranges by regional registries (RIPE for Europe, ARIN for North America, APNIC for Asia-Pacific). Companies that build these databases combine this registry data with millions of real-world data points — Wi-Fi router locations, mobile tower triangulation records, and user-submitted address confirmations — to estimate where an IP address is likely being used from. This is why accuracy improves in densely populated areas with many data points, and drops significantly in rural regions where fewer reference points exist.
Both IPv4 and IPv6 addresses can be geolocated using the same underlying registry and database techniques. However, IPv6 adoption is still uneven across countries, and many IPv6 geolocation databases are less mature than their IPv4 counterparts simply because they have collected less historical data. In practice, this means an IPv4 lookup is often slightly more reliable at the city level than an IPv6 lookup for the same connection, though both are equally accurate at the country level.
Despite what movies and some marketing pages suggest, an IP address alone is not a live tracking device. It reveals network-level information (which city or region your connection routes through), not device-level or person-level information. Anyone claiming to pinpoint an exact home address from a public IP lookup tool is either exaggerating the tool's capability or running a scam.
Does changing my Wi-Fi router change my IP location?
Not immediately. Your IP address is assigned by your ISP, not your router, so the general regional location tied to your account usually stays the same unless your ISP reassigns it.
Why does my IP show a city I've never visited?
This typically happens because your ISP's core routing infrastructure is centered in that city, even though your physical connection is elsewhere nearby.
Can two people on the same Wi-Fi have different IP location results?
No — devices sharing the same home or office Wi-Fi network share the same public-facing IP address, so they will show identical geolocation results.
