The script is written for Python 3, and you seem to be using a Python 2 
interpreter. While

dnsNB = int(data[268]/4)

would become

dnsNB = ord(data[268])/4

in Python 2 that's probably not the only change that needs to be made. For 
someone not familiar with Python the easiest fix is to install Python 3.4 
(you don't need to unistall Python 2) and to run the script as is.
