Interesting.  Does GetAdaptersInfo return a non-null PIP_ADAPTER_INFO when
there are no adapters on the (virtual) machine?  How about GetIpAddrTable?

Does the list of addresses returned by gethostbyname(gethostname()) include
the loopback address when there _are_ other adapters configured with IPv4
addresses?  (And if there are multiple loopback adapters installed/configured
then are all of their addresses included?)
