NanoIP
Your public IP, at a glance
S$ 39.98 · In-App Purchases
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.
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.
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 you that you are “safe” or “at risk”.
PRIVACY MODE
Mask the second half of every address — everywhere, or only where a screen can be read over your shoulder. Copying still gives you the whole address.
SIX APPEARANCES
System is free. Dot, Passport, Boarding Pass, Terminal and Aurora are one optional purchase. Each is a different layout and typeface, not just a different colour, so they stay recognisable even where the system flattens colour away. You can try them for 24 hours before deciding.
CITY LOOKUP, IF YOU WANT IT
Off unless you turn it on. When on, NanoIP asks its own server for the city, time zone and network type behind your address. It is the only request that ever carries your address off the device, and it is yours to switch on.
One purchase, no subscription. Questions or ideas are welcome — the address is in Settings.

New: Apple Watch support
• A watch app showing the current exit address, its location on a map, and recent exit changes, synchronized from iPhone.
• Four watch face complications and a Control Center control.
• Smart Stack prioritization when the exit changes.
• When iPhone is unavailable, the watch performs its own lookup and indicates the data source.
• All Apple Watch features are free.
Improved: status information with proxies
• An information button next to the status explains how the status was determined.
• Detection of rule-based proxy configurations that route NanoIP's own requests directly, with guidance on displaying the proxy exit instead.
• Notification when IPv4 and IPv6 traffic exit from different locations.
