Public and private addresses
What you see above is your public IP — the address every other server on the
internet sees you as, usually shared by a whole home or office. The private IP
your router hands each device, such as 192.168.0.x, is invisible from outside.
If a private range shows up in the public IP slot, you are behind a corporate network or a proxy, and a note says so.
IPv4 and IPv6
Four dot-separated numbers like 14.56.4.110 is IPv4; something with colons like
2001:0db8:… is IPv6. Where both are available the browser chooses, so the same device
can show a different address from one visit to the next.
When another site reported a different IP from this one, that difference is usually why. Going through a VPN or a corporate proxy does the same.
How much can an IP reveal?
| What it gives away | What it does not |
|---|---|
| Your ISP, a rough area (city level), the time of the visit | Your street address, your name, your phone number, which person is using it |
Geolocation services estimate position from where the ISP has allocated each range. City level is usually right; neighbourhood level is often wrong. On mobile the answer follows the cell tower and can land tens of kilometres from where you actually are.
Checking for a WebRTC leak
WebRTC, the technology behind video calls, publishes your device's private IP while it looks for a route to the other side. This used to expose your real network even with a VPN switched on.
Current browsers hide it by publishing a temporary ….local name instead.
This page shows you whether that masking is happening. If your real private IP is
visible and you use a VPN to conceal your location, it is worth looking into.
What your browser volunteers
The list further down is what a site can read without asking. Combine time zone, language, screen size and CPU core count and you have a fingerprint that recognises the same person after the IP changes. It survives clearing cookies, and resisting it takes browser-level measures such as the Tor Browser or Safari's fingerprinting protection.
Does this page send my IP somewhere?
No. It returns a value the moim.bio server already had — you connected to it to load this page in the first place. The third-party APIs that most "what is my IP" sites call are not used here, because that would hand your address to someone new.
This one tool does, unlike the others, make one request. Only a server can know your own public address, so there is no other way. Every other tool here uses no network once the page has loaded.
How do I change my IP?
Most home connections are dynamic, so powering the router off for a few minutes usually gets you a new one. To hide it properly you need a VPN or Tor — and even then your ISP still sees that you connected.
The IP will not load
Ad blockers and privacy extensions sometimes block the request. Turn one off briefly and try again.
