 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
