Ethernet Shield Fixed IP

Oh, Of course.

I made the modifications said for Pete.

I commented the line:
//IPAddress server_ip (192, 168, 15, 19);

I put my network data:

    // Mac address should be different for each device in your LAN
    byte arduino_mac[] = { 0xDE, 0xED, 0xBA, 0xFE, 0xFE, 0xED };
    IPAddress arduino_ip ( 192,   168,   15,  80);
    IPAddress dns_ip     (  8,   8,   8,   8);
    IPAddress gateway_ip ( 192,   168,   15,   1);
    IPAddress subnet_mask(255, 255, 255,   0);

Lastly I commented the line:

//Blynk.begin(auth, server_ip, 8080, arduino_ip, dns_ip, gateway_ip, subnet_mask, arduino_mac);

I used this line to enable static ip

Blynk.begin(auth, "blynk-cloud.com", 80, arduino_ip, dns_ip, gateway_ip, subnet_mask, arduino_mac);

Full Code:

   #define BLYNK_PRINT Serial


#include <SPI.h>
#include <Ethernet.h>
#include <BlynkSimpleEthernet.h>

// You should get Auth Token in the Blynk App.
// Go to the Project Settings (nut icon).
char auth[] = "YourAuthToken";

//IPAddress server_ip (10, 0, 0, 10);

// Mac address should be different for each device in your LAN
byte arduino_mac[] = { 0xDE, 0xED, 0xBA, 0xFE, 0xFE, 0xED };
IPAddress arduino_ip ( 192,   168,   15,  40);
IPAddress dns_ip     (  8,   8,   8,   8);
IPAddress gateway_ip ( 192,   168,   15,   1);
IPAddress subnet_mask(255, 255, 255,   0);

#define W5100_CS  10
#define SDCARD_CS 4

void setup()
{
  // Debug console
  Serial.begin(9600);

  pinMode(SDCARD_CS, OUTPUT);
  digitalWrite(SDCARD_CS, HIGH); // Deselect the SD card

  //Blynk.begin(auth, server_ip, 8080, arduino_ip, dns_ip, gateway_ip, subnet_mask, arduino_mac);
  // Or like this:
  Blynk.begin(auth, "blynk-cloud.com", 80, arduino_ip, dns_ip, gateway_ip, subnet_mask, arduino_mac);
}
