creating an ip out of integers

Hello,

Assume I have a 4 bytes array, can someone please tell how to create an ip out of this array? just like in

IPAddress myIP   (10, 0, 0, 4);

but the numbers coming from my byte array

IPAddress myIP   (byteArray[0], byteArray[1], byteArray[2], byteArray[3]);

Thanks, dear!
