I recently filed a bug report with Scapy, and while posting screenshots of Wireshark captures for reference, I decided to blank out my private addresses because I'm just getting into InfoSec, and am trying to be mindful of leaking potentially sensitive information:
In retrospect though, this seems overly paranoid.
I understand that private addresses aren't routable, or unique. In theory though, if someone were to gain access to my home network illegitimately, either remotely or by getting into my router via some exploit, would not knowing what subnet all the hosts exist on realistically hinder them?
My thinking is probably no, because that information could likely be found easily; either on the infected computer used as the entry point, or by some other means.
Is there any value in hiding private IP addresses in a public setting?
