Guide to setup IPv6 on Ubuntu 18.04 KVM node?

JerryHou

Noob here, I have a KVM node with 18.04 installed and IPv6 is created in provider's control panel. But I'm having troubles to get a detailed guide to setup the IPv6 address in 18.04.

When I have following command executed in console:
ping6 -c 1 ipv6.google.com

the result:
connect: Network is unreachable

I managed to find this guide: https://notepad.patheticcockroach.com/4452/how-to-enable-ipv6-on-ubuntu-server/

I setup the similar but the result was in vain, same error message. Am I missing something or could someone point me a more detailed guide on IPv6?

Thanks.

Would be helpful if you posted your current network config?

UrDN

ip -6 a s && ip -6 r s

It was very generic 50-cloud-init.yaml

network:
  ethernets:
    ens3:
      addresses: []
      dhcp4: true
      optional: true
   version: 2
