I’m facing a situation where I need to configure an interface with both a private static IPv6 address and SLAAC (Stateless Address Autoconfiguration) addresses. The reason behind this requirement is that my public IPv6 network undergoes changes, and I want the interface to obtain SLAAC addresses dynamically while also having a fixed private IPv6 address.

Is it possible to achieve this dual configuration using Netplan, and if so, how can I set it up?

Thank you very much.

  • Your business account should have a fixed IPv6 delegation.

Yes, It is possible. You should edit the netpplan configuration file (etc/netplan/config.yaml) and here is a example to achieve your goal.

  dhcp4: no
  dhcp6: no
    - "YOUR_IPV6"
  accept-ra: yes
  • This solution doesn't work.

  • I think you would need to set dhcp6 to yes, but some additional info about how it doesn't work would be useful
