I need to pass the last byte of a local IP as a parameter. Eg.: when Ethernet.localIP() returns 192.168.0.100, I need to extract the 100 and put it in a char array or string.
Anyone any ideas? Thx!
localIP() returns an
IPAddress object. That object has an operator for
 allowing you to access the individual parts of it.
IPAddress ip = Ethernet.localIP(); Serial.println(ip);
