It's not a case of cloud-init supporting IPv6 - The Amazon EC2 metadata API defines transport level details about the API - and currently only defines a well known IPv4 link local address to connect to. No well known link local IPv6 address has been defined. I usually recommend config-drive for IPv6 enabled clouds due to this. -- Sent from my Android device with K-9 Mail.
