The Xiaomi router allows you to change its LAN IP address. Sometimes, changing the LAN IP address of your router can help optimize network performance and enhance security. Xiaomi routers can only set internal (LAN) IP addresses within private IP address ranges and cannot be set to public IP addresses.
That means the router can only be configured with IP addresses in the following ranges:
10.0.0.0 - 10.255.255.255;
172.16.0.0 - 172.31.255.255;
192.168.0.0 - 192.168.255.255.
Any addresses outside these ranges cannot be set as LAN IP addresses.
