how to change ip address/on or off push button press.

actually i want to control led on off  press push button when not present wifi  device .

when press push button change link ip

192.168.0.1/light1on

or

192.168.0.1/light1onoff

here my code

#include <ESP8266WiFi.h>

WiFiServer server(80); //Initialize the server on Port 80
//io output pin configaration
int fan = 5;
int light1=4;
int light2=0;
int light3=2;
int pwmValue;
