In your usual, inimitable, "everyone ought to understand my comment"
style, Randy.

Because ".255" is very often (I'm tempted to say "almost always" a
broadcast address, and ".42" never is.  (I haven't run the numbers, but
I'm fairly certain that .42 is not the broadcast address of any size
network.)
