Questions answered

IP address FAQs

What can this IP address reveal?

An IP address can usually reveal the network provider, ASN, routed prefix and an approximate country or region. It does not reveal a precise home address or identify a person by itself.

How accurate is the IP location?

Country and network ownership are generally more reliable than city-level location. Mobile networks, VPNs and large providers can make the apparent city inaccurate.

Can I share this IP report?

Yes. Use the copy or share controls on this page. The permanent link opens the same IP intelligence report for another person.

Why can an IP address change?

Many providers use dynamic addressing. Reconnecting a router, changing networks, using mobile data or activating a VPN can change the public IP address.
