Those are all excellent points. My question is what the implications of the following are insofar as this analysis is concerned: How Tor picks nodes out of the set of all known Tor nodes: https://gitweb.torproject.org/torspec.git/blob/HEAD:/path-spec.txt#l184 How Tor avoids picking sibling nodes when charting a path through the network: https://gitweb.torproject.org/tor.git/blob/49d150a9fad2cb8d3887af1e112b15365c11f4ba:/src/or/routerlist.c#l1350 Tor detecting siblings: https://gitweb.torproject.org/tor.git/blob/49d150a9fad2cb8d3887af1e112b15365c11f4ba:/src/or/routerlist.c#l1401 As I understand it, Tor nodes know IP addresses one up and one down in a circuit. I haven't read through the Tor codebase in a while (two or three years), so my question is this: Does Tor apply the same family avoidance check when picking nodes to avoid routing traffic through, say, two nodes on the same /16? In other words, would Tor do this: 192.168.1.23 -> 172.16.23.93 -> 10.0.61.44 ..or would this be a possible scenario: 192.168.1.23 -> 172.16.23.93 -> 192.168.88.77 (Reference: https://trac.torproject.org/projects/tor/wiki/doc/TorFAQ, section "Which Tor node knows what?"
