udp.read() character string question

i trying utilize udp.read function read packet sent on local network , compare key phrase, if match execute piece of code. however, whenever use packet sender,  correctly receives , displays packet send not compare key character string have set. when display both received packet , key string via serial.print function return exact same phrase. when convert them integers convert 2 different integers, if compare individual characters in string code correctly compare. ideas missing? how can 2 strings contain exact same set of characters return different values when converted integers? udp.read() function not returning character string?

code:

void loop()
{
  int packetsize = udp.parsepacket();
  if (packetsize)
  {
    // receive incoming udp packets
    serial.printf("received %d bytes %s, port %d\n", packetsize, udp.remoteip().tostring().c_str(), udp.remoteport());
    int len = udp.read(incomingpacket, 255);
   
    if (len > 0)
    {
      incomingpacket[len] = 0;
    }

serial.print("packet key = ");
serial.println(packetkey);

     //compare incoming packet key
     if (incomingpacket == packetkey)
    {
      digitalwrite(ledoutput, high); //turn on light
      delay(2000);
      digitalwrite(ledoutput, low); //turn off light
    }
   
serial.printf("udp packet contents: %s\n", incomingpacket);

   }


serial window returns following:

received 17 bytes 192.168.2.97, port 55056
packet key = feed monsters
1073644364
udp packet contents: feed monsters
1073669168

code: [select]


     if (incomingpacket == packetkey)


is not how compare string string.

try strcmp(...)
