In the interests of precision, that should read (255.255.255.255, or 0.0.0.0).
On *my* machine, "-1" is 255.255.255.254, as it is 1's complement.

This is an easy trap to fall into, and vendors especially should be
particularly careful about this.

All the world's not a VAX, nor is it all 2's complement!
