What Is My IP — Your Address on the Internet

About the What Is My IP

Every device that reaches the internet does so through a public IP address — the identifier websites, banks and apps use to decide what language to show you, which currency to price in, and sometimes whether to let you in at all. When a site blocks your account, when a form flags your login as suspicious, when a government portal refuses connections from abroad, the conversation is really about this address. Knowing it is the first step in every such conversation, which is why every network engineer on earth keeps a what-is-my-IP bookmark.

The address alone says less than the details around it. Your ISP assigns the IP and can tell you whose network it is; geolocation databases map it to a country, city and timezone — usually accurate to the city for broadband, sometimes wildly off for mobile networks; and the ASN identifies the carrier or hosting company behind the route. Together these fields answer the practical questions: is my VPN actually on, did the mobile broadband IP rotate again, and why does this website think I am in another country.

This tool reads your public IP the moment the page loads, then enriches it with location, ISP and network details — all through public APIs called directly from your browser, with nothing stored or logged on our side. It also links straight into the deeper diagnostics: the IP address lookup for any address you paste, the ping test to measure the route from here, and the DNS lookup when the problem turns out to be names, not numbers.

How to Use the What Is My IP

Follow these simple steps — the whole process takes under a minute:

1. Open this page and read the result — detection starts automatically; there is no button to press for the basic view.
2. Check the location rows — country and city come from geolocation databases; broadband lines map accurately, mobile networks sometimes show the carrier's regional hub.
3. Note the ISP and network — this is the company your traffic rides through; a VPN user will see the VPN provider's name instead of their home ISP.
4. Toggle your VPN or proxy and reload — if the IP and ISP change, the tunnel is live; if they do not, the VPN is leaking or misconfigured.
5. Report the address, not the device — when a support agent or an admin asks for your IP, this page's first row is the exact value they need.

The Formula & Method Behind the What Is My IP

Detection is a round trip: your browser asks a public endpoint for its own address, and the server replies with the source IP it saw — which is, by definition, your public address. That is the same mechanism every website's connection log uses, which is why the number shown here is the one the outside world sees, not the 192.168 or 10.x private address your router hands your phone. NAT — the router translating many private devices onto one public IP — is why every gadget in a house shares the single address this page displays.

Geolocation is a database lookup, not a measurement. Registries allocate IP ranges to organisations by country, and commercial databases refine those ranges to cities using breadcrumbs like routing paths and DNS hints. Accuracy is excellent at the country level — above 99 percent — good at the city level for fixed broadband, and weakest on mobile networks, where a carrier may route a whole region through one hub. If the city looks wrong but the country and ISP are right, trust the ISP and ignore the city.

The network row — the organisation and ASN — is the most stable and therefore the most useful field for verification. ISPs own their ASNs for years; VPN providers have distinctive ones; hosting companies appear whenever a connection is actually a server, which is how anti-fraud systems flag suspicious logins. When this page shows a hosting company instead of a telecom, either a VPN is active or the connection is not what it claims to be — a signal worth remembering before entering passwords on a shared machine.

IP Basics Worth Knowing

Dynamic is normal. Home and mobile broadband IPs rotate every few days or on reconnection; a changed address here is not a hack, it is the ISP's design. Services that 'lock' to your IP will need updates after each rotation. Private addresses stay private. 192.168.x.x, 10.x.x.x and 172.16-31.x.x never appear on the public internet; if a form asks for 'your IP' it almost always wants the public one this page shows.

IPv6 is arriving quietly. Many networks now hand out both an IPv4 and an IPv6 address; some sites see one, some the other, which explains why two websites can show two different addresses for the same device minutes apart. Privacy note: this page calls public APIs from your browser and displays what they return — no values are stored, but never treat an IP as a secret; treat this page as a mirror the outside world already has.
