Where are IP addresses stored on Android?

Question

Where are IP addresses stored on an Android device? In what location on disk, or otherwise; how are they stored?

The user of your device can set a static ip for every wifi connection in the settings. — greenapps, Jul 17 '14 at 17:42
On my device it is not possible to set a static IP in the settings. — JohnyTex, Jul 17 '14 at 18:06

For statically configured networks (i.e., not DHCP which doesn't store), addresses are stored in /data/misc/wifi/ipconfig.txt, managed by WifiConfigStore class. This is not a public API and is only used from class WifiStateMachine. However, you can find out the format of this file by viewing the source: WifiConfigStore.java.

I think this may be device-dependent. – JohnyTex May 24 '18 at 08:01

Because Android is based on a Linux System, the IPs are stored inside the system. So it's the same way like in Linux ( keyword: ifconifg )

But you can get the IP like shown here: IP details

I want to set a static persistent IP for my device. Where is the config file for that located then? Can't find anything. – JohnyTex Jul 17 '14 at 13:14
Can I configure a persistent static IP address for a specific interface using setprop? – JohnyTex Jul 17 '14 at 13:27
Yeah it was way more informative before the edit disappeared. – JohnyTex Jul 17 '14 at 18:02

IP addresses on Android are normally stored as an entry in: /data/data/com.android.providers.settings/databases/settings.db

sqlite database.
