The word, nword, long, and nlong properties return values in host or network byte order.

that is, word returns it in word format (16bit) in host byte order, nword returns it in word format (16bit) in network byte order
long returns it in long format (32bit) in host byte order
nlong returns it in long format (32bit) in network byte order

Although from personal testing, I believe it always returns the same byte order no matter which one you use, but I could be mistaken.
