Your Public IP Address
Processed on our server. What you enter is sent over an encrypted connection, calculated, and returned. It is never written to a database or logged, and nothing is retained once the result is sent. Avoid entering passwords, API keys or other secrets. How we handle data
Public vs Private IP Addresses
The address shown above is your public IP — the one the rest of the internet sees when your network makes a request. It almost certainly is not the address your own device thinks it has.
Inside a home or office network, each device gets a private address from a range reserved for internal use: 192.168.x.x, 10.x.x.x, or 172.16–31.x.x. These ranges are not routable on the public internet, which is why every home router in the world can hand out 192.168.1.1 without conflict. Your router performs Network Address Translation (NAT), rewriting outbound traffic so it appears to come from the single public address your provider assigned.
This is why every device in your house shows the same public IP here, while each reports a different address in its own network settings.
IPv4 and IPv6
IPv4 — four numbers, e.g. 203.0.113.42
32 bits, giving about 4.3 billion possible addresses. That sounded limitless in 1981 and ran out in practice around 2011, which is the entire reason NAT and carrier-grade address sharing became universal.
IPv6 — eight hex groups, e.g. 2001:0db8:85a3::8a2e:0370:7334
128 bits, giving roughly 340 undecillion addresses — enough that every device can hold a globally unique one without NAT. Consecutive zero groups collapse to :: for readability, which is why real addresses often look shorter than the full form.
Why you might see either
Most networks now run both side by side. Which one appears here depends on which protocol your browser preferred for this particular connection, so the answer can genuinely change between visits or between networks.
What Your IP Does and Does Not Reveal
An IP address is routing information, not identity. It reliably indicates which provider carries your traffic and, usually, a rough geographic region — often only to the city or provider hub, which can be a long way from where you actually are.
It does not reveal your name, your street address, or what you are doing online. Your internet provider can connect an address to an account, but that record is not publicly accessible and is normally released only under legal process.
Two things commonly make geolocation wrong. A VPN shows the exit server’s location rather than yours. And many mobile and some fixed-line providers use carrier-grade NAT, sharing one public address across thousands of subscribers — so the location shown may be a regional gateway rather than anywhere near you.
When You Actually Need This
The usual reasons are practical: adding your address to a server firewall or database allowlist, confirming a VPN is actually routing traffic before you rely on it, diagnosing why an API is rate-limiting you, configuring remote access to a home machine, or checking whether your provider has changed your address after a router restart.

We do not log your IP address. It is simply reflected back to you for diagnostic or network testing purposes.

When you visit this page, your browser sends a request to our server. We simply read the origin IP from the request headers and display it back to you.
In-Depth Analysis & Reference Data
Whether you're behind a NAT, router, or VPN, the address shown is what the wider internet sees. This is a common requirement for developers managing server access or troubleshooting API rate limits based on IP.
Registry Questions & FAQ.
Why does my IP change?
Many ISPs use dynamic IP addresses, which means your IP might change periodically or when you restart your router. A static IP remains exactly the same.
Do you store this information?
No, we do not log, track, or save your IP address. It is strictly used to display the output to you directly without any persistent storage.
