When you bind a socket to the wildcard address(i.e. 0.0.0.0), you're
listening simultaneously on all interfaces so you can't ask for "the"
host address because there might be more than just one. Furthermore, the
socket doesn't keep trace of the local interfaces that were active when
it was created.
