It's the address the rest of the internet sees your connection coming from. Every device on your home Wi-Fi usually shares the same public IP address. Your router gives each device its own private address inside the house (like 192.168.1.20), which is why the address in your network settings is different from the one shown here.
IPv4 is the original format, four numbers like 203.0.113.42, and the world ran out of them years ago. IPv6 is the newer, much longer format with room for every device. Most connections now have both, and browsers use IPv6 when they can. When a website, game server or support person asks for your IP address, they almost always mean IPv4, so that's the one I show first.
Most phones and computers use IPv6 privacy addresses: the second half of the address changes regularly, often every day, so websites can't follow one device around by its address. The first half, your network's prefix, stays the same. If you need an address that stays put, for a firewall rule for example, use your IPv4 address.
It's an estimate of where your internet provider's network is, from an IP location database, not from GPS. It's usually right about the country and region, but the city can be off, sometimes showing the nearest large city instead of yours. It never shows a street address.
I compare the time zone of your IP address's location with your device's clock. When they don't match, your traffic is probably leaving through a VPN, a proxy, a work network or a privacy service like iCloud Private Relay somewhere else. If you've turned one of those on, that's expected, and it's a quick way to check it's working.
I check which versions Google, Microsoft and Mozilla are currently releasing for your platform. New versions roll out to people gradually over a week or two, so a version that's still being released counts as up to date. Safari updates along with macOS and iOS, so for Safari and other browsers I show the version without a verdict.
The resolution shown is the number of pixels your screen really has. Most modern screens use scaling (Retina on a Mac, iPhone or iPad, display scaling on Windows) so text isn't tiny, which makes apps and websites treat the screen as if it were smaller. A Mac with a 3456 × 2234 screen at 2× scaling lays things out as if it were 1728 × 1117. The window size is in those scaled units, which is what websites use for their layout.
No. Your addresses are looked up through Cloudflare, which already delivers every page of my site, and through my own server. This page doesn't save your addresses or device details, and doesn't send them to any other lookup service. Your browser and screen details are read in your browser and never leave it.
IP & Device can also go in the Tools menu on my homepage, next to a speed test, a password generator, a file converter and more.
