Description (last modified by teor)

See Proposal 312: Tor Relay Automatic IPv6 Address Discovery:
https://gitweb.torproject.org/torspec.git/tree/proposals/312-relay-auto-ipv6-addr.txt

The child tickets are in proposal section order, but they will probably be implemented in this order:

Dependencies:

  • Propose and implement IPv6 ORPort reachability checks on relays (O1.1, #33048)

Pre-Implementation:

  • Test IPv4 Address Detection using Chutney (O1.3, #33250)
  • Detailed Address Resolution Logs

Explicit IPv6 Configurations:

  • Make the Address torrc Option Support IPv6 Literals
  • Use Advertised ORPort IPv4 and IPv6 Addresses in Descriptors
  • Use Local Interface IPv6 Address

Directory Authority Security:

  • Stop Directory Authorities Resolving *Port Hostnames
  • Limit Directory Authority Addresses to Address and ORPort

Remote IPv6 Information:

  • Make the Address torrc Option Resolve IPv6 Hostnames
  • Use Own Hostname IPv6 Addresses
  • Use Directory Header IPv6 Addresses
  • Update Directory Spec for IPv6 X-Your-Address-Is

Auto IPv6 ORPort:

  • Automatically Enable an IPv6 ORPort
  • Add an AddressDisableIPv6 torrc option
  • Publish IPv4 Descriptor on Guessed IPv6 Reachability Failure

Internal Testing:

  • Test Relay IPv6 Addresses Discovery using Chutney (O1.3, #33251)

Public Tor Network Testing:

  • Test Relay IPv6 Addresses Discovery on the Tor Network
  • Ask Relay Operators to Test IPv6 Addresses Discovery
