The relay search tool displays data about single relays and bridges in the Tor network. It provides useful information on how relays are configured along with graphs about their past.

The aggregated search tool displays aggregated data about relays in the Tor network. It provides insight into diversity in the network and the probabilities of using relays in a particular country or AS as a guard, middle or exit relay. The results are restricted to only currently running relays and do not include bridge data.

The advanced search tool allows you to build advanced queries to search for data about single relays and bridges in the Tor network or aggregated data about currently running relays. For single relays, it provides useful information on how relays are configured along with graphs about their past. Aggregated data provides insight into diversity in the network and the probabilities of using relays in a particular country or AS as a guard, middle or exit relay filtered by the search parameters.

You can search for Tor relays and bridges by using keywords. In particular, this tool enables you to search for (partial) nicknames (e.g., “moria”), IP addresses (e.g., “128.31.”), and fingerprints (e.g., “9695DFC3”). It is also possible to combine searches, e.g., “moria 128.31.”. Finally, you can use qualifiers to search for relays in specific countries (e.g., “moria country:us”), with specific contact information (e.g., “contact:arma”), or with specific flags (e.g., “flag:Authority”).

If you are searching for a bridge, you will need to search by the hashed fingerprint. This prevents leaking the fingerprint of the bridge when searching. You can find this in the hashed-fingerprint file in the Tor data directory. On Debian systems, this is in /var/lib/tor but may be in another location on your system. The location is specified as DataDirectory in your torrc.
