Where is the Internal IP address stored in Ubuntu?
Is there some file in the Linux-Ubuntu filesystem that contains the internal IP of the machine running it? Ideally, is the output provided by the following command
hostname -I
saved somewhere in the filesystem?
(thanks to How do I find my internal ip address?)
You can find a tree in /proc/net/fib_trie
Otherwise you can look it up with a tool such as ip addr
