IP address lookup
An IP address carries a surprising amount of context: the country and city it is routed from, the network operator, and whether it belongs to a home connection, a mobile carrier or a datacenter. That last point is what fraud teams care about, because almost nobody signs up for a consumer service from a server rack.
This tool returns the geolocation, ISP and network for any public IP, along with the datacenter, proxy and VPN flags. Coordinates and postal code are unlocked on the API. Private and reserved ranges are identified as such rather than located.
What you get back
Location. Country, region, city and timezone. Accurate to the city in most cases, never to a household.
Network. ISP, organization and ASN, which tells you whether the connection is Comcast at home or AWS in a datacenter.
Anonymity flags. Datacenter or hosting, proxy, VPN and Tor. Any of these on a signup or a payment is a risk signal.
Coordinates (API). Latitude, longitude and postal code for teams that map or geofence.
How to use it
- Enter the IP from your logs, your analytics or your signup record.
- Press Look up IP.
- Compare the country and timezone to what the user claimed. Compare the network to what a real customer would use. Datacenter plus a mismatched country is the pattern to hold for review.
Who uses this
Fraud and risk teams. Datacenter IPs, proxy flags and country mismatches are the three fastest signals for a bad signup or order.
Analytics and localization. Country and timezone drive currency, language and send-time decisions.
Support and security. Checking the IP on a suspicious login tells you in seconds whether it came from a VPN in another continent.

How accurate is IP geolocation?
Country is reliable. City is usually right for fixed broadband and often wrong for mobile carriers, which route traffic through regional hubs. Never treat it as a physical address.
Why does my own IP show a different city?
Your ISP routes your traffic through a point of presence that may be in a neighboring city. That is normal.
What does the hosting flag mean?
The IP belongs to a datacenter or cloud provider range. Legitimate users on VPNs and corporate networks can trigger it, but so do bots and fraud rings.
Does it support IPv6?
Yes. Paste the full address.
Can I look up the IP of a domain?
Not on this page. Resolve the domain first, or use the MX lookup for the mail side.
