It seems a bunch of people seem to think this is the default ip for softap mode, when it is not. 192.168.4.1 is the default, but it does look like this IS the default ip by lib when ip config fails. Any ideas why, and why not use the same ip as SDK https://github.com/esp8266/Arduino/blob/dd6333ee8b26dd9cc82dea252ba150e85c0ebb11/libraries/ESP8266WiFi/src/ESP8266WiFiAP.cpp#L173
