IP address FAQs

Does an IP Passport reveal a home address?

No. An IP address can indicate a network and approximate service area, but it does not reveal a person or precise home address.

How accurate is the city shown for an IP address?

City data is approximate and often identifies an ISP service area. Country and network ownership are generally more reliable.

What does Refresh IP data do?

It recalculates this address with the newest locally installed datasets and may queue a bounded background city check.

Can I share this IP Passport?

Yes. The permanent report link can be shared with a colleague, provider or support team.
