Ah, correct. I'd forgotten that.

Because your block of eight is set up as a separate network, and without
a gateway, you'd have no way to send your packets to the rest of the
world.

The question you could ask, though, is, while you need a broadcast
address for your network (7, if you take your broadcast address modulo
8), and the router to the rest of the world will take an address (1, on
Usen), why do you need a network address (0)? Admittedly, some old stuff
will break when trying to communicate with it when attached to the local
network, but most things will work.

Lucky you! I'd kill for this.
