NanoIP shows the public IP address your iPhone is actually using — IPv4 and IPv6 together — and says plainly how your traffic is reaching the internet.

EVERY APPLE DEVICE
NanoIP runs on iPhone, iPad, Mac and Apple TV, with a free Apple Watch app. The appearances are one purchase that unlocks on all of them, and your exit history follows you through your own iCloud.

ON THE MAP
See where your exit surfaces. A soft disc over the country when that is all the on-device database knows; a point when you switch city lookup on. Both address families, and a line between them when they surface in different places. Positions come from the address, never from Location Services.

HISTORY
Every change of exit is kept — a new network, a VPN coming up or going down — as a timeline, a map of every place your exits have been, and a “Passport”: countries, networks, time spent on VPN. Stored on your iPhone and, if you like, in your own iCloud private database, which nobody else can read. Delete a row or clear it all at any time.

THIS DEVICE
Your side of the connection, drawn as a path: device — interface — tunnel, if there is one — gateway — DNS — exit. Then every interface that has an address, with each address labelled global, private or link-local, and the path's own flags: IPv4, IPv6, expensive, Low Data Mode. No permission asked; nothing here leaves the device.

LOOK UP ANY ADDRESS
Type an IP address or a domain: country, network, reverse DNS, whether it answers on port 443, and its place on the map — against the same offline databases.

SHARE IT
One tap turns the exit into a card made for a chat: the address large, the country and network, a map of where it surfaces, the time, and the app’s name. Privacy mode masks the address and drops the map before anything leaves.

TOLD WHEN IT CHANGES
Turn on alerts and NanoIP notifies you when it notices a different exit — best effort, whenever iOS lets it check.

APPLE WATCH
Your exit on the wrist: the address, where it surfaces and the latest changes, sent from your iPhone. Four complications and a Control Center control. Free, like every widget.

WIDGETS, EVERY SIZE, FREE
Small, medium and large on the Home Screen. Circular, rectangular and inline on the Lock Screen. StandBy on the nightstand. A one-tap control in Control Centre. Every size is free, and stays free.

RESOLVED ON THE DEVICE
Country and network are looked up in a database that ships inside the app. Your address is not sent anywhere to be identified. No account, no ads, no tracking, no subscription.

IPv4 AND IPv6, SIDE BY SIDE
Most tools show one of them. NanoIP shows both — and when one is missing it says which is true: that this network does not carry it, or that nothing answered. Those are different facts and they deserve different words.

KNOW YOUR EXIT
NanoIP reads the local network path to tell whether this device is going out through a VPN or a proxy, and labels an exit that belongs to a hosting network. It describes what it sees. It never tells
