Look Up the Caller IP Address

What request resolves the caller?

The route ends at /ip. Adding an address changes the request to an explicit lookup.

curl -H "Authorization: Bearer YOUR_API_KEY" https://api.iprout.com/ip

How are proxies handled?

The API resolves the caller using the request address and trusted proxy configuration, including forwarded address information supplied by trusted infrastructure.

When should I use this endpoint?

Choose caller lookup for server-side personalization, regional defaults, analytics enrichment, or request context.

• Do not use the result as proof of identity
• Expect VPNs and proxies to affect the result
• Ask for user confirmation before applying important regional decisions

How should caller IP resolution be implemented?

Use the path ending at /ip when the network peer calling IPRout is the address you intend to resolve. A backend request normally resolves that backend or its trusted forwarding path, not automatically the browser visiting your application. Keep this responsibility close to the IPRout client so the behavior documented in Look Up the Caller IP Address remains consistent across web requests, workers, and scheduled jobs.

How should caller IP resolution be verified?

Compare calls from a workstation, production server, and proxied application to understand which address reaches the API. Test trusted proxy configuration at your own application boundary before relying on forwarded client information. Automate the stable cases and reserve live checks for controlled environments so verification is repeatable without consuming unnecessary production allowance.

How should caller IP resolution be operated?

Document whether the feature needs the service address or an end-user address. That decision determines whether caller lookup is correct or whether your server should validate an observed address and use explicit lookup. Write down the owner and expected behavior so an alert or product change can be handled without reconstructing the original integration decisions.

Where does caller IP resolution stop?

Caller IP location is approximate network context. It can suggest language or timezone, but VPNs, mobile gateways, relays, and corporate egress make it unsuitable as proof of identity or physical presence. Treat that limit as part of the feature contract and direct callers to the related guide when they need a different guarantee or control.

What belongs in the release review for caller IP resolution?

Review the deployed implementation of Look Up the Caller IP Address, not only a local sample. Confirm the intended endpoint, credential source, timeout, response model, and fallback from the environment that will carry real traffic. Use the verification cases above as release evidence, inspect generated browser assets and logs for secret exposure, and make sure dashboards identify the workload without storing raw credentials or unnecessary IP data. Record the configuration owner and rollback action before enabling the feature broadly.

When should caller IP resolution be revisited?

Revisit caller IP resolution when traffic volume, plan capacity, application ownership, deployment regions, browser origins, data retention, or the product consequence of a lookup changes. Compare the current implementation with the documented operating boundary rather than assuming the original decision still fits. Update tests and internal runbooks together, then verify the public API contract and related IPRout guides before rolling the change across every service that shares the client or account.
