What Is My IP Address?

A public IP address is the address your ISP assigns to your internet connection. It is visible to any server you connect to and is used to route traffic back to your device. It differs from a private IP address, which only exists within your local network (such as 192.168.x.x) and is not routable on the public internet. This tool displays your public address, not your private one.

When your browser loads this page, it makes an HTTP request to the server. The server reads the source address of that request, or the value in the X-Forwarded-For header if your connection passes through a proxy or load balancer. That address is returned as your detected IP. No browser plugin, script permission, or user action is required.

IPv4 is a 32-bit addressing format that produces addresses like 203.0.113.1. The total number of unique IPv4 addresses is around 4.3 billion, a pool that is largely exhausted. IPv6 uses a 128-bit format, producing addresses like 2001:db8::1, which allows for a vastly larger address space. This tool detects and displays whichever format your current connection uses. Some connections support both, and the displayed type reflects which protocol your device negotiated for this session.

Geolocation data is derived from the registered location of your IP block, not from your physical device. ISPs often register large blocks of addresses at a regional headquarters or data center, which may be in a different city than where you actually are. Mobile networks and corporate networks can add further discrepancy. Country-level accuracy is generally high, but city-level data should be treated as approximate.

When a VPN is active, your traffic exits through the VPN provider's server before reaching the internet. The tool will display the IP address of that exit node, along with the ISP, organization, and geolocation associated with it. Your original ISP-assigned address is not visible. This is why checking your IP address after connecting to a VPN is a common way to confirm the VPN is working correctly.

An Autonomous System Number (ASN) is a unique identifier assigned to a network operator, such as an ISP or a large organization. It is used in the Border Gateway Protocol (BGP) to manage how traffic is routed between networks on the internet. Displaying the ASN alongside your IP helps identify which network operator owns the address block you are using. For deeper ASN research, the ASN Lookup tool provides more detail on any given number.

The tool detects your IP address to display it to you in the browser. For details on what data is retained, how long it is kept, and under what conditions it may be processed, refer to the privacy policy . The geolocation lookup is performed against an external database to resolve the network fields shown on screen.

This tool detects your public IP address and returns geolocation and network metadata for it. It does not judge whether the address belongs to a proxy, VPN, or data center. The proxy check tool takes an IP address and evaluates it against proxy and VPN detection signals, returning a verdict on whether the address is likely a proxy exit node. Use this page to find your address, and the proxy check to assess what type of connection it represents.

Most residential ISPs assign dynamic IP addresses, meaning the address can change when your router reconnects to the network, after a lease period expires, or when your ISP reallocates address blocks. This is standard behavior. Static IP addresses, which do not change, are typically a paid option or are reserved for business accounts. If your address changes frequently, it affects services that whitelist by IP, such as remote access systems.

This tool only detects the IP of your own current connection. To find the IP address of a domain or hostname, use a DNS lookup, which resolves the A or AAAA record for that domain. The DNS Lookup tool on this site handles that query and returns the address records associated with any domain you enter.

The ISP field reflects the registered owner of the IP block in the geolocation database, which may be a parent company, a wholesale network provider, or a transit provider rather than the retail brand you signed up with. Corporate networks often route through a company's registered network rather than a consumer ISP. If you are on a mobile network, the displayed ISP is typically the carrier's registered network entity, which may differ from the brand name you know.

Yes. The tool detects whichever public IP your mobile carrier assigns to your session. Mobile carriers often use carrier-grade NAT, meaning many devices share a small pool of public addresses. The IP displayed is the address visible to the public internet for your session, not a unique address for your handset. Geolocation accuracy on mobile networks tends to be lower than on fixed broadband, as carrier address blocks are often registered at regional hubs.
