What is my IP address?
Your address is below, with your User-Agent and connection details. No cookies, no ads, no third-party scripts.
216.73.216.140
This is the address the internet sees. You reached v4x.me over IPv4, so your IPv6 address is not shown. What is the difference?

Get your IP from the command line
Ask for this page with curl and you get the bare address — no HTML, no JSON to unwrap, no flags to remember. That makes it usable directly inside a script.
$ curl v4x.me 216.73.216.140
Assign it to a variable in one line:
$ MY_IP=$(curl -s v4x.me)
Every endpoint is documented on the API page. There is no key, no sign-up and no rate limit.
What this page can and cannot tell you
The address, the protocol, the network name and the rough location all come from the connection itself. They are accurate because your connection carries them.
The city is a guess. It is derived from who owns the address block, so it often names the location of your provider rather than yours. Treat it as a region, not a position. If you use a VPN it describes the VPN server instead.
Frequently asked questions
What is my IP address?
Your IP address is the number the internet uses to send data back to you. Your provider assigns it to your connection. Every site you open sees it, because a reply cannot reach you without it. The address at the top of this page is the one the internet currently sees.
Why does my IP address change?
Most home connections get a dynamic address. Your provider leases it for a period and can give you a different one when the lease ends, when your router restarts, or when you move to another network. A static address stays the same and usually costs extra. Mobile networks change your address often.
What is the difference between IPv4 and IPv6?
IPv4 addresses look like 203.0.113.42 — four numbers and three dots. There are about 4.3 billion of them and they ran out. IPv6 addresses look like 2a02:a44f:1e2f:1::7 and use hexadecimal separated by colons. The supply is effectively unlimited. Most connections now support both.
How do I find my IP address from the command line?
Run curl v4x.me. It prints the bare address and nothing else, so you can put it straight into a variable or a script. It works the same on Linux, macOS and Windows. No flags and no parsing are needed.
Does this site store my IP address?
This site writes nothing to a database, sets no cookie, and runs no third-party tracker or advertising script. The address is read from the request and written into the page sent back to you. Cloudflare serves the site and keeps short-term request logs for debugging, in the same way any hosting provider does.
Can someone find my home address from my IP address?
No. An IP address maps to a rough area, usually the city or region of your provider, and sometimes the wrong city entirely. It does not reveal a street address or a name. Only your provider can link an address to an account, and they need a legal order to hand that over.
Does a VPN change my IP address?
Yes. A VPN sends your traffic through its own server, so sites see that server address instead of yours. Load this page with the VPN on and off, and you will see two different addresses.
What is a User-Agent?
The User-Agent is a line of text your browser sends with every request. It names the browser, its version and your operating system. Sites use it to serve the right layout. It is also how a site can tell you are on a phone.
