About IP Address Lookup

IP Address Lookup checks a public IPv4 address against the ip2region IPv4 database and returns the available country, region, city, and network-provider fields. Use it to inspect your current public IP or a specific IPv4 address; database-based geolocation is an approximate network reference, not a precise physical location.

Reference: ip2region IPv4 database and project documentation

01

How to use it

  1. Choose Current public IP to inspect the address seen by the service, or enter one valid IPv4 address such as 8.8.8.8.
  2. Run the lookup and review the returned country, region, city, and network-provider fields together; an empty field means the database has no value for that level.
  3. Use the result for network diagnostics or a rough regional reference, then verify decisions involving security, access control, compliance, or billing with the authoritative system.

Frequently asked questions

What does an IP address lookup show?

This tool maps a public IPv4 address to the country, region, city, and network-provider information available in its database. It does not identify a person or guarantee a street-level location.

Why can an IP location be different from my actual location?

IP ranges are assigned and routed by networks, so VPNs, mobile carriers, corporate gateways, carrier-grade NAT, stale records, and database coverage can make the returned location approximate or different from where a device is used.

Does this tool support IPv6 addresses?

No. The current lookup uses an IPv4 database and accepts IPv4 input only. IPv6 addresses should be checked with a service or database that explicitly supports IPv6.

03

Lookup scope and result interpretation

The tool checks the current public IPv4 address or an IPv4 address you enter, then returns the country, region, city, and network-provider fields available in the ip2region database. Treat each field as network-attribution information, not a precise determination of a device or person’s location.

Example check: look up 8.8.8.8 and the current public IP separately. For troubleshooting, record the lookup time, complete IPv4 address, and returned fields, then compare them with the network egress, VPN, or carrier information.
