What is my IP address?

What a public IP address tells websites

A public IP address identifies the connection your traffic uses on the public internet. It may belong to your home ISP, mobile carrier, workplace, cloud server, VPN provider or proxy service. Websites use it to route responses back to you, apply security checks, estimate location, enforce regional rules and detect suspicious traffic patterns.

Your public IP is different from private local addresses such as 192.168.x.x, 10.x.x.x or 172.16.x.x. Private addresses work inside a local network, while the public IP is what external websites see after your router, carrier network or VPN gateway forwards the request.

Why your IP can change

Many residential and mobile providers assign dynamic IP addresses. Your IP can change when the modem reconnects, your mobile network changes, a VPN is enabled, or your ISP rotates addresses. Business internet, servers and hosting platforms often use static IP addresses that stay the same for longer periods.

IP location, ISP and ASN

IP location is an estimate based on network databases. It can often identify country, region and city, but it is not GPS. ISP shows the provider or organization announcing the address. ASN, short for Autonomous System Number, identifies the routed network responsible for that IP block.

These fields are useful for confirming whether a VPN is active, checking a server region, debugging content localization, or understanding why a service thinks you are connecting from a particular country.
