The Tor dataset tracks the IP addresses participating in the Tor network, with a flag distinguishing exit nodes, whose addresses actually originate user traffic, from middle relays that never do.
It is rebuilt continuously from the Tor consensus so new relays appear and retired ones disappear within a day.
The data
Inside the file
One record per row, a commented header line first. This is what ipregistry-tor.csv looks like:

| Column | Description |
|---|---|
ip_start | First IP address of the range, IPv4 or IPv6. |
ip_end | Last IP address of the range, inclusive. |
is_exit_node | Whether the range operates as a Tor exit node (true) or a relay only (false). |
The MMDB variant carries the same data in a memory-mapped binary tree, compatible with the standard MMDB reader libraries available for every major programming language.
