Turns out, I'm off by one _again_.  Sheesh. :P

The number of records in the file should be (224*2^24)-1, which *20 is 
75161927660 bytes.

Filesize is actually 75161927360 bites, leaving 300 bytes unaccounted 
for.  300/20 = 15 records.

So it is just as I said in my previous post, _except_ 224.0.0.0 wasn't in 
the original set -- I just go up to 223.255.255.255.

(224.0.0.0- are multicast addresses.)

Anyway, I know exactly where the error was.  The only reason I would 
mention something so trivial is that I want Fibian to see what computer 
science really looks like.
