That looks like the Mac address, not the IP address.

I actually have some code wrapping rtnetlink socket, which can get you
lots of routing information (man 7 rtnetlink). Although I use this code
to query the bandwidth manager on live machines, the code has a memory
leak, is alpha quality and fairly incomplete. I think rtnetlink is
pretty much Linux specific too.

If there is enough interest to pump up my motivation, I'll try to finish
it.
