ESP8266-Based Serial WiFi Shield

Hello,

I am new to IoT and Arduino and exploring it for some project.

Background: I am using Arduino Uno board along with ESP8266-Based Serial WiFi Shield. I am able to transfer simple "High" from my Laptop and other way round. I am communicating with default IP - 192.168.4.1

Requirement: I would need multiple Arduino boards on one LAN (single network) so that they can communicate with each other. I am just wondering how all the boards including my laptop will connect on same network. Will they all connect to "DoitWiFi_Config"? If yes what will be the IP Address of each of the device?

Can you please suggest the correct approach?

Thanks!
