How it works

  1. 1
    Public IP from upstream

    We query a public IP info API to detect the address your traffic exits from.

  2. 2
    GeoIP database mapped

    ISP, ASN, country, region, and city come from a maintained GeoIP database.

  3. 3
    All client-side

    The lookup runs from your browser — we never store your IP server-side.

Real use cases

  • — Verify a VPN or proxy is actually changing your exit IP.
  • — Confirm geo-routing for CDN or testing edge nodes.
  • — Whitelist your IP in firewall, database, or API allowlists.
  • — Triage which network a remote worker is connecting from.
