** Description changed: + [Impact] + Ubuntu users concerns with privacy of their IP addresses over IPv6. + + [Test case] + 1) Configure netplan with IPv6 privacy enabled: + + network: + version: 2 + ethernets: + eth0: + dhcp6: true + ipv6-privacy: true + + 2) Run 'netplan apply' + 3) Run 'ip -6 addr' + 4) Verify that additional temporary addresses are added by the kernel. + + [Regression Potential] + Minimal. This enables or disables the setting for IPv6 privacy addresses on an per-interface basis, and defaults remain unchanged. + + --- + + Summary: netplan contains no configuration entry that allows one to enable IPv6 Privacy Extensions (RFC 4941) when autogenerated (DHCPv6 stateless, SLAAC) addressing is used. This should map to the IPv6PrivacyExtensions entry for systemd-networkd (man systemd.network, [Network] section), and the ipv6.ip6-privacy entry for NetworkManager (https://developer.gnome.org/NetworkManager/stable /settings-ipv6.html).
