What is an IP lookup?
An IP lookup maps an IP address to the information behind it. For 8.8.8.8, for example, the lookup reports the country and city the geolocation database associates with the block, the network operator (Google) and the autonomous system number 15169 that announces the route. It also shows approximate coordinates and timezone when the database holds them, plus the reverse hostname if one is published.
An IP address identifies a network connection, not a person. Geolocation is approximate: VPNs, mobile carriers and corporate proxies routinely place a device hundreds of kilometres from where it really is. The page also reports your own public IP, the fastest way to see what the internet sees when you connect. Country and registry data are precise; city and coordinates are estimates.
How to use the IP lookup
- Leave the field empty to look up your own public IP automatically.
- Or paste any IPv4 or IPv6 address you want to investigate.
- Read the geolocation, ISP and ASN fields for the returned network.
- Use the map and country data to judge whether the location is plausible.
Frequently asked questions about IP addresses
Why is the location sometimes wrong?
Geolocation databases attach an address to the city where the operator registered it, not where the device is; VPNs, mobile networks and proxies make the reported location hundreds of kilometres off.
What is an ASN?
An Autonomous System Number identifies the network, usually an ISP, hosting provider or large company, that announces a block of IP routes; it tells you who owns the address.
Can I find a person from an IP address?
No. An IP address identifies a connection at a point in time, not a human; only a court order to the ISP can tie it to a subscriber account.
