Is there a way to access WiFi IP and connect/disconnect/scan functions from the uC?

[spotrevoc]

I need my device to function relatively independent of a computer/browser. Sometimes, especially during rolling blackouts, my network's DHCP ends up reassigning IPs and it can be a pain to figure out the new IP of an esp-link device. At the very least, is there a way to retrieve the IP through the el-client library? If possible, it would be really good to be able to disconnect, scan, and connect with ssid/password from the microcontroller side rather than through a browser.
