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.

Practical checks to run

Start by checking whether your visible IP is IPv4, IPv6 or both. Then compare the displayed ISP and region with the network you expect to be using. If you are connected to a VPN, the public IP, country and ASN should usually match the VPN provider rather than your home or mobile ISP.

If a website blocks access, shows the wrong country, or keeps asking for extra verification, your IP reputation, ASN type or location estimate may be part of the reason. In that case, compare your result with and without VPN, check whether DNS is resolving to the expected region, and inspect browser information to see whether language or device settings conflict with your network location.

Common situations where IP checks help

VPN verification: after connecting to a VPN, reload the IP checker and confirm that the country, ISP and ASN changed. If only the browser location changed but the public IP did not, the VPN may not be active for that browser or network interface.

Server and hosting checks: when deploying a website or API, use the lookup to confirm which public IP and ASN are associated with the server. If the IP belongs to an unexpected provider, DNS may still point to an old host, a CDN, or a proxy layer.

Account security reviews: many services show recent login IPs. Comparing those records with your current public IP can help you understand whether a login came from your home network, mobile network, workplace, VPN, or a location you do not recognize.

Regional content problems: streaming services, search engines, payment pages and account systems may use IP location to select content or apply risk checks. If the displayed region is wrong, the issue may be an IP database mismatch rather than your device location.

FAQ

Can my public IP reveal my home address? No. It can often show an approximate network region, but it does not reveal your street address by itself.

Why does my IP show a nearby city instead of my real city? IP databases usually map provider network blocks, not exact devices. Nearby cities, ISP hubs and routing locations are common.

Does private browsing hide my IP? No. Private browsing mainly affects local browser history and cookies. A VPN or proxy changes the public IP seen by websites.

Why does my phone show a different IP than my computer? Phones may use mobile carrier networks, Wi-Fi, private relay features or VPN profiles. Each path can expose a different public IP.

Can two people share the same public IP? Yes. Home routers, office networks, public Wi-Fi and carrier-grade NAT can place many devices behind one public IP address.
