The point of my wish is, when ip address dialog appear - default value filled with last ip address i have used before. so i'm not type full of ip segment (again). only have to change 4th segment of the ip because other segment never changed.
Our DHCP has reservations for all Devices.
Every device get the same IP address everytime the device connects to our Wireless Lan. I can use the last used IP in B4A as the ip of the device does not change here as DHCP always give it the same IP.
