No, you are correct, neither the original file nor the munged file
contain IP addresses per se. But they do contain a whole bunch of
32-bit numbers. And one of those 32-bit numbers in the original file
just happened to be 0xD856C325. (If the data is random, this will
occur once in every 4G transferred). And 0xD856C325 just happens to be
the IP address of the router in question. So, since the router can't
distinguish between the IP address 0xD856C325 and anything else that
might look like 0xD856C325, it goes ahead and assumes that it's an IP
address and munges the data.

Was that more clear? Or did I misunderstand your post?
