IP Address FAQ

Open our homepage and your public IP address is shown instantly at the top of the page, along with your ISP and approximate location. It's the address your ISP assigns to your connection and the one every website sees when you visit.

A private IP (like 192.168.1.42) identifies a device inside your own network and is not reachable from the internet. A public IP identifies your whole network to the internet and is assigned by your ISP. Websites only ever see the public one — the find-your-IP guide shows how to see both.

IPv4 addresses (203.0.113.42) are 32-bit numbers with about 4.3 billion combinations, and the world has run out. IPv6 addresses (2606:4700::1111) are 128-bit with a practically unlimited space. Modern networks run both side by side — our IPv4 vs IPv6 guide compares them in detail.

No. An IP address can usually be traced to a city or region and to your internet provider, but not to your street or house. Only your ISP can link an IP to a specific customer, and it only does so for legal reasons. See for yourself with the IP location map.

IP geolocation is based on databases mapping address ranges to places, and the reported city is often where your ISP's routing equipment sits rather than where you are. City-level accuracy is typical; street-level accuracy is impossible from an IP alone.

On the public internet, no — addresses must be unique. Inside a private network many devices share one public IP through NAT while each holds its own private address like 192.168.1.x. That's why a whole household appears online under a single public IP.

Most home connections use dynamic IPs that change whenever the router reconnects or its DHCP lease expires — often every few hours or days. Business lines and paid static-IP services keep the same address indefinitely.

Yes — a VPN, proxy or the Tor network replaces the address websites see; rebooting a router with a dynamic IP may also hand you a new one. Traffic from these services is often detectable, so verify any address afterwards. The hide-your-IP guide compares all the options.

Your router has two: a private gateway address (commonly 192.168.1.1 or 192.168.0.1) used to open its settings page, and the public WAN IP it uses on the internet. The gateway can be found with ipconfig on Windows or in your phone's Wi-Fi details — the router IP guide walks through it.

Check instantly with the free IP Blacklist Check: it queries major spam and abuse DNSBLs live from your browser and reports every hit, plus how to request removal.

Detection databases flag addresses that relay traffic — VPN servers, Tor exits, hosting providers, or occasionally misconfigured home routers. If your ordinary home IP is wrongly flagged, it usually clears as the databases update. Run the Proxy & VPN Check to see your own status.
