How to use
- Enter a public IPv4 or IPv6 address; do not enter a URL, hostname, private address, or personal identifier.
- Run the lookup. DEA sends only the IP address required for the external GeoIP query.
- Review the ISP or organization, ASN, country/region, city, coordinates, and time zone that the provider makes available.
- Treat geographic fields as estimates and confirm network ownership with RDAP or routing data when accuracy matters.
Examples
- Input
8.8.8.8- Output
Public network, organization/ISP, ASN, and estimated country or region
A public resolver address normally maps to the operator's network rather than a particular user.
- Input
2001:4860:4860::8888- Output
IPv6 network and estimated GeoIP fields when supported
IPv6 coverage and granularity can differ from IPv4 coverage.
- Input
192.168.1.10- Output
No public GeoIP result
RFC 1918 private addresses are meaningful only inside a local network and are not globally geolocatable.
Understanding the result
ISP or organization names the network operator associated with the address block. It may be a cloud, CDN, VPN, mobile carrier, or enterprise network instead of the end user's access provider.
ASN is the autonomous system number used to identify a routing domain on the internet. An ASN describes network routing ownership, not a device or person.
Country/region, city, coordinates, and time zone are database estimates for an address block or network exit. City-level results can be distant from the actual device.
A changed result does not necessarily mean the device moved: providers reassign addresses and GeoIP databases update at different times.
Common errors and limitations
- VPNs, proxies, Tor exits, and corporate gateways normally reveal the exit network rather than the user's original location.
- Mobile carrier NAT and shared broadband addresses can represent many users and may be registered in a different city or region.
- GeoIP databases can be incomplete, stale, or inconsistent between vendors; do not use a city or coordinate as proof of residence or identity.
- The queried IP is sent to the DEA server and an external data provider. Do not use the tool for unauthorized tracking or high-stakes access decisions.
Frequently asked questions
- What is an ISP lookup?
- It maps a public IP address to published network ownership or connectivity data, often including an organization name and autonomous system.
- What is an ASN?
- An autonomous system number identifies a network that presents a common routing policy to the internet. It does not identify an individual subscriber.
- How accurate is IP geolocation?
- Country-level data is often more stable than city-level data, but no GeoIP result should be treated as GPS or a verified street address.
- Why does a VPN show another country?
- The lookup sees the VPN exit address, so the result describes that server's network and estimated location.
- Can a private IP be located?
- No. Private ranges such as 10.0.0.0/8 and 192.168.0.0/16 are reused inside many networks and have no unique public GeoIP location.
