I wrote a command in C++ that interrogates the TCP/IP stack directly to |
| 12 |
obtain the IP address of any given interface. I wrote it some years |
| 13 |
ago, so it's only IPv4 at the moment; it will take a day or two to add |
| 14 |
IPv6 support. |

I can send you the source code if you want. Likewise to any other |
| 17 |
interested reader -- or I can post it here as a mail attachment, since |
| 18 |
it is quite tiny. |
