There are many projects out there that produce a list of Tor exit IPs, but this one is the best. For us. Definitely. This is useful.

This scanner is better than all the all the rest because it does everything to find as many IPs exits may use as possible:

• It records ORPort IPs (both v4 and v6) from the server descriptors of all relays that can exit to OFTC infrastructure, regardless of whether or not they have the Exit flag.

• Through the relays that can connect to OFTC's user-facing ircds, we build circuits and connect to an ircd in order to get it to report to us what hostname/IP we are coming from. If we get a hostname, we lookup its A and AAAA records.

• For all relays that can connect to OFTC infrastructure, we see if the IPs in their descriptors have rDNS entries, and if so, we lookup A and AAAA records.

To be explicit: "OFTC infrastructure" includes our user-facing ircds and our web irc client. For relays that can only exit to our web IRC client, we only check their descriptors and do DNS queries.

This will install Tor IP Scanner and its dependencies into a virtualenv suitable for development work.

$ cd to/this/directory
$ python3 -m venv venv
$ . venv/bin/activate
$ pip install -U pip
$ pip install -e .[dev]

Start the scanner with toripscanner scan. It runs in the foreground and stays running forever, periodically scanning new relays.

Periodically run toripscanner parse data/results/* to parse the scanner's results into a plaintext list of IPv4/6 addresses. The command only uses "recent" results even if the input files it reads contain old results.
