all is OK, you did this probably on x86 CPU which is little endian. on 
powerpc it would be 01020304 as it is big endian.

to write endian independent code:

man htonl

all these are macros actually.

"network order" is big endian. so eg htonl would reverse order on x86, and 
ddo nothing on powerpc.
