Overview - - Most of the time, Tor treats user-specified hostnames as opaque: When - the user connects to www.torproject.org, Tor picks an exit node and uses - that node to connect to "www.torproject.org". Some hostnames, however, - can be used to override Tor's default behavior and circuit-building - rules. - - These hostnames can be passed to Tor as the address part of a SOCKS4a or - SOCKS5 request. If the application is connected to Tor using an IP-only - method (such as SOCKS4, TransPort, or NATDPort), these hostnames can be - substituted for certain IP addresses using the MapAddress configuration - option or the MAPADDRESS control command. - -2. .exit - - SYNTAX: [hostname].[name-or-digest].exit - [name-or-digest].exit - - Hostname is a valid hostname; [name-or-digest] is either the nickname of a - Tor node or the hex-encoded digest of that node's public key. - - When Tor sees an address in this format, it uses the specified hostname as - the exit node. If no "hostname" component is given, Tor defaults to the - published IPv4 address of the exit node. - - It is valid to try to resolve hostnames, and in fact upon success Tor - will cache an internal mapaddress of the form - "www.google.com.foo.exit=64.233.161.99.foo.exit" to speed subsequent - lookups. - - The .exit notation is disabled by default as of Tor 0.2.2.1-alpha, due - to potential application-level attacks. - - EXAMPLES: - www.example.com.exampletornode.exit - - Connect to www.example.com from the node called "exampletornode". - - exampletornode.exit - - Connect to the published IP address of "exampletornode" using - "exampletornode" as the exit. - -3. .onion - - SYNTAX: [digest].onion - - The digest is the first eighty bits of a SHA1 hash of the identity key for - a hidden service, encoded in base32. - - When Tor sees an address in this format, it tries to look up and connect to - the specified hidden service.
