You assume that you already have a network address.

Think about 255.255.255.255 as a link local address that needs to
be scoped to be meaningful. Then you have three options:

- only allow it to broadcast packets to all interfaces.
- use some definition of 'default interface'
- extend the API to specify an interface

The first is rarely what you want, the latter won't happen.
