Look up where an IP address is registered and who operates it, yours, or any address you paste in.
IP geolocation works from registration databases: address blocks are allocated to providers, and databases maintain an approximate location for each block, usually the provider's point of presence or the area the block serves. Accuracy is good at country level, decent for large cities, and unreliable at street level: no public IP lookup can pinpoint a house, whatever pop-up ads claim. The result also shows the operating organisation (ISP or company), the network block (ASN), and the time zone the block is associated with.
VPNs and mobile networks shift apparent location, a VPN user appears wherever the VPN exits, and mobile addresses often geolocate to a distant hub city. Treat the answer as 'where this address is registered and routed', not 'where the person is'. For your own current address as the outside world sees it, the on-site What Is My IP tool is the one-field version of this page.
Can an IP lookup find someone's home address? No. Public lookups resolve to a city area and an ISP. Exact subscriber addresses are held by the ISP and released only under legal process.
Why does my location show a different city? Your provider routes traffic through regional hubs, and geolocation databases place the block at the hub or the provider's registered location. It is normal for the city to be tens of miles off.
Does this work for IPv6? Yes, paste a full IPv6 address and the same registration data is returned where the database covers it.
