Detecting your IP address...

What Is an IP Address?

An Internet Protocol address identifies an interface for IP communication. The public source address visible to a site can represent a shared NAT, carrier gateway, VPN, proxy, or hosting egress rather than one device. IPv4 is specified by RFC 791 and IPv6 by RFC 8200.

IPv4 vs IPv6

IPv4 addresses are 32 bits and IPv6 addresses are 128 bits. The displayed address is the public source address Cloudflare reports for this request. Source: IETF RFC 8200.

Public vs Private IP Addresses

Your public IP is the source address this site sees. It may be shared by multiple customers or devices through NAT or carrier-grade NAT. Private addresses such as 192.168.x.x and 10.x.x.x are not routed as public internet source addresses. This tool does not read your device's private address.

How to Protect Your IP Address

A VPN, Tor exit relay, or proxy can make a website see that service's public egress address instead of the address normally used by your access network. Encryption, logging, and routing behavior varies by provider; an IP lookup alone cannot verify those properties.

Frequently Asked Questions

What public IP does this page show?

It shows the source address available with this request. It may identify a shared NAT, carrier gateway, proxy, or other egress rather than one device.

What is the difference between IPv4 and IPv6?

IPv4 addresses are 32 bits under RFC 791. IPv6 addresses are 128 bits under RFC 8200. This page displays the family observed for the request.

Can someone find my exact location from my IP address?

The city, region, postal code, and coordinates shown here are request metadata estimates and may be missing or wrong. Do not treat them as precise device or street location. Source: Cloudflare request metadata documentation.

How do I change the public IP websites see?

A VPN, Tor exit relay, or proxy can present its own public egress address. An IP lookup cannot verify the provider's encryption, logging, or privacy behavior.

Does my public IP address change?

It can remain stable or change according to the provider, network, and egress in use. Compare observations over time and consult the provider for its assignment policy.

What can someone infer from my IP address?

A service can associate the source address with network ownership and estimated request geography. The address alone does not prove a person's identity, physical address, device type, or whether a VPN is active.

What is the difference between public and private IPv4 addresses?

The public address is the source address visible to this site and may be shared through NAT. Private-use IPv4 ranges are defined in RFC 1918 and are not read by this tool.
