IP address is
192.168.43.1 by default and there is no option to change it permanently. Is it possible to change it without root access?

Note: Adding / removing IP address requires root access.
Before Android Pie, tethering IP (
192.168.43.1) was hard-coded (1, 2). But now it's randomized on each session(3). You can use Android's builtin
ip command to set an additional fixed IP address (within same subnet obviously):
~# ip address add 192.168.43.100/24 dev wlan0
del to delete.
Make sure that the name of your Wi-Fi interface (
wlan0 usually) is correct. Check with
ip link or
ls /sys/class/net or
The problem with above approach is that the added IP is not permanent. Once you switch OFF the hotspot, IP will get cleared. So you can use an
init trigger to set IP address whenever hotspot is turned ON. Add these lines to
(/vendor)/etc/init/hostapd.android.rc file (or any
.rc file under
on property:init.svc.hostapd=running exec - -- /system/bin/sleep 2 exec u:r:magisk:s0 -- /system/bin/ip address add 192.168.43.100/24 dev wlan0
hostapdis the system service which manages access points.
dnsmasq starts listening on all IP addresses which are set on WiFi interface before
dnsmasq is started. But with both above methods there is no way to make sure that IP is added after
netd sets up the interface and before
dnsmasq starts. So the added IP address may conflict with IP leased to another host (saved in
/data/misc/dhcp/dnsmasq.leases) by DHCP server (
dnsmasq up to Pie) from DHCP range (
192.168.43.254 by default) (4).
To address this problem:
dnsmasq.conf. See How can I permanently assign a static IP address to Wi-Fi or USB tether clients?
dnsmasqwith a shell script to achieve this. See How to change the default hotspot DHCP IP address range?
/system/bin/dnsmasq with a shell script which adds IP address before executing original
dnsmasq binary. Rename
dnsmasq.bin and create script:
#!/system/bin/sh # set fixed IP address on Wi-Fi interface ip address add 192.168.43.100/24 dev wlan0 # execute original binary exec dnsmasq.bin $*
netstatto make sure that DHCP server is listening on reserved IP address (or on all IP addresses i.e.
0.0.0.0) so that to avoid IP address collision.
NOTE that in order to modify
/system partitions need to be mounted R/W which requires
dm-verity disabled. Otherwise you may use bind mounts (used by Magisk modules). On non-SAR devices
/init.rc can also be edited to modify
/init.rc file in ramdisk by unpacking
