I don't know if it's written explicitly anywhere. But the semantics do support
it's use as 'any address' or 'any address here'. bind() for example, uses it
this way to bind to all addresses on a host. I seem to recall a couple other
similar usages which would support the impression that 0.0.0.0 would mean 'this
host'.

Really speaking though, it's just a magic cookie. A reserved address
interpreted in a variety of ways. Certainly there is some software out there
that treats it as 'no address'.
