How to tell if an IP address has been used as a Tor exit node

[Man]

The Tor network provides anonymity to Internet users by hiding their real IP addresses through multi-layer encryption and redirecting traffic through various nodes. There are three types of nodes in this network: entry, intermediate and exit. The last one is the node from which user traffic goes out to the open Internet. If any unwanted activity was carried out through the Tor exit node, then it is the IP address of this node that may appear in the logs and raise suspicions. This is where ExoneraTor comes in - a service created by the Tor project to check whether a specific IP address was used as an exit node of the Tor network on a certain date and time.

Was the IP address used as a Tor exit node?​

ExoneraTor collects data about exit nodes of the Tor network and stores it in its database. If an IP address was an exit node at the time of any action, then you can get this information from the service. The service makes available Tor network logs, which include data on all known exit nodes for previous months and years. This makes it easy to find out whether an IP address was used as an exit node at a specified time.

To use ExoneraTor you need:

1. Go to the site.
2. Enter the IP address and the time period you are interested in.
3. Press the search button and get the result.

If the IP address was an exit node of the Tor network at the specified time, ExoneraTor will display the corresponding information.

ExoneraTor has some limitations: it only provides information for a limited period of time, and may not always have complete data on all network nodes due to changes in the Tor infrastructure.
