[PLUG] Raising the dead: proc filesystem

Reference to an original thread "proc filesystem":
http://lists.netisland.net/archives/plug/plug-2002-12/msg00478.html

Has anyone found a decent way to do this outside of parsing ifconfig output?  I've done it in a one liner here...
http://www.linuxquestions.org/questions/blog/sag47-492023/using-a-script-to-get-your-ip-address-35251/

Yet I've found that most times I'm able to reliably turn to the /proc filesystem for stuff like this.  I'm just curious if anyone has found a decent way to do this since that thread was originally posted.

I wonder if parsing a combination of /proc/net/fib_trie and /proc/net/route would be useful in finding the IP address of the default route (which I would assume be the internet connected IP address).  I found fib_trie by grep -irl my IP address through /proc.  Here's some kernel documentation on fib_trie but there's nothing useful about using it for obtaining the IP address of the default route.

I look forward to discussing this.
