I wrote a command in C++ that interrogates the TCP/IP stack directly to
obtain the IP address of any given interface.  I wrote it some years
ago, so it's only IPv4 at the moment; it will take a day or two to add
IPv6 support.

I can send you the source code if you want. Likewise to any other
interested reader -- or I can post it here as a mail attachment, since
it is quite tiny.
