~From within a C program, what is the best way to determine if a
particular IP address belongs to the host the program is running on? The
host may be a router, so it can have an arbitrary number of interfaces
and IP addresses, and it might not use DNS. The program runs as root,
so I can use weird low-level kernel interfaces if necessary.

If possible, I need this to work on both Linux 2.4 and Linux 2.6, but
other systems aren't as important at the momment.
