Just the containers I use.

If using IPv6 with docker remember to enable support by adding this to /etc/docker/daemon.json

{
  "experimental": true,
  "ip6tables": true
}

For podman see How to configure Podman 4.0 for IPv6

1. Install netavark

2. Set network_backend = "netavark" in /etc/containers/containers.conf

3. The default podman0 bridge does not have IPv6 defined and DNS disabled.

4. Create a new bridge podman network create --ipv6 podman1

5. Examine bridge: podman network inspect podman1

6. The new bridge should have this defined:

       {
             "subnet": "fd96:7c2e:b8d2:bf65::/64",
             "gateway": "fd96:7c2e:b8d2:bf65::1"
       }
   ],
   "ipv6_enabled": true,
