See Proposal 313: Relay IPv6 Statistics: https://gitweb.torproject.org/torspec.git/tree/proposals/313-relay-ipv6-stats.txt Tor's IPv6 reachability checks are described in: Proposal 311: Tor Relay IPv6 Reachability: https://gitweb.torproject.org/torspec.git/tree/proposals/311-relay-ipv6-reachability.txt The child tickets are in proposal section order, but they will probably be implemented in this order: Dependencies: * Prop 311: 5. Declare Support for Subprotocol Version "Relay=3" (O1.1, legacy/trac#33226) Implementation: * Write a Script that Counts IPv6 Relays in the Consensus Metrics Review: * Check IPv6 Relay Consensus Counts Script Internal Testing: * Test IPv6 Relay Consensus Counts using Chutney (O1.3, legacy/trac#33267) Public Tor Network Testing: * Test IPv6 Relay Consensus Counts on the Tor Network Monitoring: * Monitor IPv6 Relay Counts in the Consensus Children: * [x] tor#33262 Prop 313: 3. Write a Script that Counts IPv6 Relays in the Consensus * [x] trac#33266 [Prop 313: 7.2. Show IPv6 Relay Counts on Consensus Health ](https://gitlab.torproject.org/tpo/metrics/consensus-health/-/issues/33266) * [x] tor#33268 Prop 313: 8.1. Test IPv6 Relay Consensus Counts on the Tor Network * [x] trac#33269 [Prop 313: 8.1. Check IPv6 Relay Consensus Counts Script](https://gitlab.torproject.org/tpo/metrics/analysis/-/issues/33269) * [x] tor#33270 Prop 313: 8.1. Monitor IPv6 Relay Counts in the Consensus
