Let's Control It

Hi, one little question.
Why webserver ip is fixed to 192.168.4.1?
WebServer.send(200, "text/html", "<meta HTTP-EQUIV='REFRESH' content='0; url=http://192.168.4.1/setup'>");
and not obtained from the assigned (DHCP or fixed configurated) IP from the config?

because, in that case for ex, i have to mantain netmask opened to reach that ip, that is different to my network base address

I am not sure what release you are using, but all of mine only have that address when no AP is assigned, or if they are unable to connect.
192.168.4.1 is the default setup address. Connect to the AP vis WiFi then enter that address.
