#22300: DNSstuff (http://www.dnsstuff.com/) occasionally indicates a different IP address from the exit node IP address indicated in the Torbutton menu --------------------------------------+--------------------------- Reporter: cypherpunks | Owner: tbb-team Type: defect | Status: closed Priority: Medium | Milestone: Component: Applications/Tor Browser | Version: Severity: Normal | Resolution: not a bug Keywords: | Actual Points: Parent ID: | Points: Reviewer: | Sponsor: --------------------------------------+--------------------------- Changes (by yawning):
* status: new => closed * resolution: => not a bug Comment: This less a bug and more a limitation of what information is available to Tor Browser through the tor daemon. The circuit display's idea of an node's IP address is based off the address that the ORPort is listening on, because that's the only information contained in the directory documents. There's no requirement for any node to use the same address that the ORPort is on, to make outgoing connections (this applies to all nodes, but is particularly relevant for exits). So any Exit IP listing will always give incorrect results, if the only data source is "the list of ORPort IPs". Some of the other tools like check.tp.o attempt to discern the true exit IP by building test circuits through the network, however that approach is entirely inappropriate for something to include in Tor Browser. See https://gitweb.torproject.org/tordnsel.git/tree/src/TorDNSEL/ExitTest for an example of how this is implemented. -- Ticket URL: <https://trac.torproject.org/projects/tor/ticket/22300#comment:1> Tor Bug Tracker & Wiki <https://trac.torproject.org/> The Tor Project: anonymity online _______________________________________________ tor-bugs mailing list tor-bugs@lists.torproject.org https://lists.torproject.org/cgi-bin/mailman/listinfo/tor-bugs
