I’m afraid the snippet pointed by Ralph is incorrect, as INADDR_ANY should not
be a valid return for inet_addr. Here is a quick check on different OSes.
On Linux, the man Page states:
> If the input is invalid, INADDR_NONE (usually -1) is returned.
On Mac OS X:
> The constant INADDR_NONE is returned by inet_addr() and inet_network() for

On Windows things are slightly more complicated:

Thus, we should compare with INADDR_NONE and not with INADDR_ANY.
