Yes. And what is wrong with that assumption?
I know that others are arguing about when you don't have an address yet, 
but that is a can of worms with headaches that also needs to be sorted 
out. But for me, I just reacted to the way a broadcast was changed into 
a directed broadcast by the OS without me asking it to.

That would actually be rather nice. I didn't think of that one, but it 
would actually perhaps make the most sense.

There already is. At the moment, some interface is chosen. However, the 
destination address is then changed to be a specific broadcast on that 
interface's network broadcast address, which is what I'm objecting to.

Ugh! No thanks... :-)

Why wouldn't the first one be what I want?
