What is a private IP address?

A private IP address is one reserved for use inside local networks and never routed on the public internet: 10.0.0.0/8, 172.16.0.0/12, 192.168.0.0/16 and, for IPv6, fc00::/7. Your router translates between these and your single public address (NAT). The address shown at the top of this page is always the public one.

Can someone do anything with your IP address?

With only your IP address, someone can see roughly where you are (city-level), which provider you use and whether the address is on any blocklist. They cannot find your home address or your identity from it alone, and they cannot "hack" a device just by knowing it. The realistic risks are targeted denial-of-service attacks against gamers and streamers and being blocked by sites that dislike your provider. See what can someone do with your IP address.

Can two cell phones have the same IP address?

Yes. Mobile carriers commonly place thousands of phones behind one public IPv4 address using carrier-grade NAT, so two phones on the same network can show the same public address at the same time. Inside the carrier's network each phone still has its own private address, and with IPv6 each phone usually gets a unique public address.

What is my IP address on my phone?

Open this page on your phone: the address at the top is your phone's current public IP, on Wi-Fi or on mobile data. To see the private address your phone has on Wi-Fi, go to the network's details in your settings (iPhone: Settings › Wi-Fi › the network; Android: Settings › Network › the network › Advanced). The guide how to find your IP address on any device has screenshots-free steps for every system.

Is 192.168.1.1 my IP address?

No. 192.168.1.1 is a private address, almost always the login address of your home router. Your public IP — the one shown on this page — is assigned by your provider and never starts with 192.168. The guide 192.168.1.1 router login explains what you can do at that address.

What this means, in plain English

This address belongs to a datacenter or hosting network (Amazon.com, Inc.), which is how a VPN, cloud server or corporate gateway usually looks to websites. This is where the server is, not where you are.

IP location is approximate: it points to the area around Columbus, United States, never to a street address.

Learn more about what you see

Your public IP address

The address at the top of the page is what every website, app and server sees when you connect. It is assigned by your internet provider (or by your VPN when one is active), not by your computer. Copy it with one tap when support asks for it.

IPv4 address

The familiar four-number form, for example 203.0.113.42. Most home connections still use one shared IPv4 address for every device in the house; many mobile networks share one address between thousands of customers (carrier-grade NAT).

IPv6 address

The newer, longer form, for example 2001:db8:85a3::8a2e:370:7334. We fetch it from an IPv6-only host so the page can show both families even when your browser prefers one. If this line stays empty, your connection has no working IPv6 today — that is normal for roughly half of all users.

Your IP location and ISP

Below the address you see where the address is registered to and who operates it. Every value names the database it came from and when that database was last updated, because no two sources agree on everything.

City, region and country

We compare several geolocation databases (DB-IP Lite, IP2Location.io and, for your own address, Cloudflare's live edge data) and show how many of them agree; registry records are listed separately because they give the network owner's country, not a location. IP location is approximate: city-level at best, never a street address. Read why IP location can be wrong.

ISP, organization and ASN

The ISP is the company that announces your address on the internet; the ASN (autonomous system number, written AS plus a number) is its routing identifier. We take the ASN from the live BGP table (iptoasn.com, Team Cymru and RIPEstat agree on it almost always) and the organization name from the registry. See what is my ISP.

Hostname (reverse DNS)

The PTR record your provider attached to the address, such as 203-0-113-42.example-isp.net. Many ISPs encode the city or the connection type in it; many leave it empty. It is looked up live from public resolvers.

Is your connection private?

This block answers the question most visitors actually have: does the internet see my real connection, or a VPN, proxy or Tor exit? The verdict is built from published lists and our own measurements, and it always says how confident it is.

VPN, proxy and Tor detection

We check your address against the Tor Project exit list, commercial VPN and data center ranges, the official cloud provider feeds, Apple's iCloud Private Relay list and several DNS blocklists that flag open proxies. A home or mobile ISP address is reported as residential or mobile; a hosting range as data center. Run the full proxy and VPN checker for the evidence behind the verdict.

DNS and WebRTC leak quick check

If you use a VPN, the address on this page is only half the story. The quick check runs a short DNS leak test against our own test zone and asks your browser for its WebRTC addresses. A mismatch means something bypasses the tunnel. The dedicated VPN test runs the extended versions of both.

What your IP address reveals

An IP address on its own reveals the network it belongs to and, through geolocation databases, the area it is usually used in. It does not reveal your name, your street or your browsing history to a random website. Combined with other signals — cookies, browser fingerprint, account logins — it becomes one more way to recognize a returning visitor. Your ISP, on the other hand, can tie the address to your account, which is why it matters who can see your DNS queries and which sites you visit. The guide what can someone do with your IP address goes through the realistic risks without the scare stories.

IPv4 vs IPv6: which are you using?

Both addresses above are yours at the same time if your provider offers dual-stack. IPv4 is the 1980s format that ran out of free addresses years ago; IPv6 has room for every device to get its own public address again. Websites that support both will usually prefer IPv6 when your connection does. The IPv6 test shows which family your browser actually prefers and whether each one works end to end; IPv4 vs IPv6: what is the difference? explains the formats.

Public vs private IP

The address on this page is your public address. Inside your home or office network every device also has a private address such as 192.168.1.20 or 10.0.0.5 that never leaves your router. Both are real IP addresses; only the public one identifies you on the internet. Details in public vs private IP addresses.

Dynamic vs static IP

Most consumer connections get a dynamic address that can change when the router reconnects or after a lease expires; business lines and servers usually pay for a static one. If your address looks different from last week, that is usually all it is. See static vs dynamic IP addresses.

How to hide or change your IP

To change your public address, reconnect your router (dynamic connections often get a new one), switch between Wi-Fi and mobile data, or ask your provider. To hide it from websites, route your traffic through a VPN, a proxy or Tor; each shows the websites the service's address instead of yours, with different trade-offs in speed and trust. Whatever you choose, come back to this page afterwards: the address and the verdict at the top tell you immediately whether it worked, and the VPN test tells you whether anything still leaks. Guides: how to change your IP address and how to hide your IP address.

Frequently asked questions

Does my IP address change?

Usually yes. Home and mobile connections get a dynamic address that can change when your router reconnects, when the lease expires or when you move between networks. Some providers keep the same address for months; others rotate it daily. A static address only changes when you or your provider change it.

What is a dynamic IP address?

A dynamic IP address is one your provider assigns from a pool for a limited time (the lease). When the lease ends or the connection drops, you may receive a different address from the same pool. It is the default for consumer internet because it needs no manual configuration.

Does every device have an IP address?

Every device that talks on a network has an IP address, but not every device has its own public one. At home, your router holds the public address and gives each phone, laptop and TV a private address such as 192.168.1.x. On mobile data, the carrier often shares one public address between many customers.
