This data comes from "extrainfo" descriptors published by relays.
You can see them all at https://metrics.torproject.org/data.html

Or said more clearly, The Tor Project does not have any logs, so the
logs we don't have don't have IP addresses. :)

You might find http://freehaven.net/anonbib/#wecsr10measuring-tor
interesting for a discussion of the sorts of data the relays collect
and why we think it's safe / worthwhile.

And you might like https://research.torproject.org/techreports.html
for the write-ups we've done about various ways to try to count
users despite not having much info about anything.
