About IP Address Info
The IP Address Info tool looks up what is publicly known about an IPv4 or IPv6 address: the city, region, and country it geolocates to, the ISP or hosting provider that owns it, its ASN, timezone, and currency. Leave the field blank and press the button and it tells you the same about your own connection. It is a quick way to identify where a suspicious address in your access logs came from, confirm what a VPN is presenting to the outside world, or see how a visitor is likely to be geolocated by a CDN. Lookups are performed by the public ipapi.co service, so the address you enter is sent there.
Key features
- Geolocation to city, region, and country, with country code and calling code
- Network ownership: the ISP or hosting provider, plus the ASN behind the address
- Timezone, UTC offset, and local currency for the location
- Latitude and longitude, and the postal code where the data has one
- One-click "look up my IP" for checking what your own connection presents publicly
- Works for both IPv4 and IPv6 addresses
- Every field has its own copy button, so you can pull one value into a ticket or a firewall rule
- Clear error messages for a private address, a malformed one, or a rate-limited response
- Note: lookups are performed by the public ipapi.co API, so the address you enter is sent to that service
How to use it
- Type the IPv4 or IPv6 address you want to check.
- Press Lookup, or use the my-IP button to check your own connection instead.
- Read the location, network, and timezone details in the results list.
- Copy any individual field you need for a ticket, a log annotation, or a block rule.
Tips & common mistakes
- IP geolocation is an estimate, not a fact. City-level accuracy is often right for residential connections and frequently wrong for mobile networks, satellite links, and corporate VPNs, where the exit point can be in another country entirely.
- The ASN and network owner are far more reliable than the city. Knowing an address belongs to a datacentre provider rather than a residential ISP usually tells you more about suspicious traffic than the pin on a map.
- Private ranges — 10.x, 172.16–31.x, 192.168.x, and 127.x — cannot be looked up. They are not routable on the internet and no public registry knows anything about them.
- Never use geolocation alone for access control or fraud decisions. A VPN changes the answer in one click, and legitimate users are misplaced often enough to matter.
- The my-IP button shows your public address as seen from outside — the right way to confirm a VPN or proxy is doing what you think it is.
- This uses a free public API with rate limits. A lookup that fails after several in a row is usually throttling rather than a problem with the address.
- Cloud provider addresses are reassigned constantly. An address that geolocates to one region today may have been serving something entirely different last month.
- Need to resolve a hostname to its DNS records instead? Use the DNS Lookup Tool.
- Working out which subnet an address falls in? Use the IPv4 Subnet Calculator.
