How to get data via socket on FRDM-K66F from laptop using ethernet cable ?

Hello, I am using FRDM-K66F Microcontroller. I want to use FRDM-K66F as a client and accept data from a laptop using Ethernet cable. The confusing part is, How to get the IP number of MIcrocontroller. I am trying to use the following program from mbed. At the server side, the python program is which sends the data.

******** Program Start************

1. include "mbed.h"
2. include "EthernetInterface.h"

const char* ECHO_SERVER_ADDRESS = "192.168.2.2"; const int ECHO_SERVER_PORT = 7;

int main() { EthernetInterface eth; eth.init(); Use DHCP eth.connect(); printf("\nClient IP Address is %s \n", eth.getIPAddress());

UDPSocket sock; sock.init();

Endpoint echo_server; echo_server.set_address(ECHO_SERVER_ADDRESS, ECHO_SERVER_PORT);

char out_buffer[] = "Hello World"; printf("Sending message '%s' to server (%s)\n",out_buffer,ECHO_SERVER_ADDRESS); sock.sendTo(echo_server, out_buffer, sizeof(out_buffer));

char in_buffer[256]; int n = sock.receiveFrom(echo_server, in_buffer, sizeof(in_buffer));

in_buffer[n] = '\0'; printf("Received message from server: '%s'\n", in_buffer);

sock.close();

eth.disconnect(); while(1) {} } *******Program End**********

1) How to get the IP address of Microcontroller? 2) Can I use this program for FRDM-K66F? 3) Can I use threading in this program?
