+const char* g_DhcpHostName = ""; // ***** NEW code line
+void DhcpClass::send_DHCP_MESSAGE(uint8_t messageType, uint16_t secondsElapsed)
+</code>

+	// ***** start NEW code lines
+	if( strlen( g_DhcpHostName ) > 0 ) {
+		buffer[17] = strlen(g_DhcpHostName);
+		strcpy((char*)&(buffer[18]), g_DhcpHostName);
+	}
+	else {
+	// ***** end NEW code lines
