Frequently asked questions

What is a public IP address?
The address your router presents to the internet, and the one that every website you visit can see. It is different from the private address your device uses inside your home network — every device in your house shares one public IP, which is why they all show the same one here.
Does my IP address reveal my home address?
No. It can typically be geolocated to a city or region, and sometimes not even accurately — a great many people are placed in whatever city hosts their ISP's equipment. It does not reveal your street address. Your internet provider knows which customer an address was assigned to, and will disclose that only to law enforcement with proper legal process.
Why does my IP address change?
Most home connections use dynamic addresses, reassigned periodically by the ISP from a shared pool. Restarting your router will often get you a new one. Business connections frequently pay for a static address, which stays fixed because servers need to be findable at a consistent location.
What is the difference between IPv4 and IPv6?
IPv4 uses 32-bit addresses — the familiar four numbers separated by dots — and provides about 4.3 billion of them, which the internet exhausted years ago. IPv6 uses 128-bit addresses and provides a number so vast it is effectively unlimited. The two coexist during a transition that has been under way for well over a decade.

What your IP address actually gives away

The popular imagination overstates this considerably. Your IP address identifies your connection, not you, and it reveals your internet provider and an approximate geographic area — often the right city, sometimes merely the right region, and occasionally somewhere you have never been because the geolocation database is guessing from the ISP's registration. It does not reveal your name, your address, your identity or what you were doing. Your ISP holds the record linking the address to your account, and disclosing that requires legal process. What is genuinely worth knowing is that your IP is visible to every server you connect to, and is a stable-enough identifier over short periods to link your activity across sites — which is precisely why advertising networks find it useful.

The fingerprint is more revealing than the address

The information beneath your IP address on this page is, in aggregate, the more interesting privacy story. Your browser voluntarily tells every site your operating system, browser version, screen resolution, time zone, language, installed fonts and graphics hardware quirks. Individually these are unremarkable; combined, they form a browser fingerprint that is very often unique across millions of users, and that persists even when you clear cookies, use private browsing or change IP address via a VPN. This is why a VPN alone is a partial defence at best — it changes the address you connect from and leaves the fingerprint entirely intact. Browsers such as Tor deliberately make every user look identical for exactly this reason, and it is a considerably harder problem than hiding an IP.
