# IPv6-Support for Docker
**Note**: IPv6 networking is only supported on Docker daemons running on Linux hosts. So it is neither supported on Windows nor on macOS.
Before you can use IPv6 in Docker containers or swarm services, you need to enable IPv6 support in the Docker daemon. Afterward, you can choose to use either IPv4 or IPv6 (or both) with any container, service, or network.
## Docker on Linux and Docker-rootless
1. Edit `/etc/docker/daemon.json` (or `~/.config/docker/daemon.json` in case of docker-rootless), set the `ipv6` key to `true` and the `fixed-cidr-v6` key to your IPv6 subnet. In this example we are setting it to `2001:db8:1::/64`. Additionally set `experimental` to `true` and `ip6tables` to `true` as well.
```json

sudo systemctl restart docker
```
You can now create networks with the `--ipv6` flag and assign containers IPv6 addresses using the `--ip6` flag.
## Docker Desktop (Windows and macOS)
On Windows and macOS which use Docker Desktop, you need to go into the settings, and select `Docker Engine`. There you should see the currently used daemon.json file.
1. You need to now adjust this json file by setting the `ipv6` key to `true` and the `fixed-cidr-v6` key to your IPv6 subnet. In this example we are setting it to `2001:db8:1::/64`. Additionally set `experimental` to `true` and `ip6tables` to `true` as well.
```
"ipv6": true,
"fixed-cidr-v6": "2001:db8:1::/64",
"experimental": true,
"ip6tables": true
```
2. Add these values to the json and make sure to keep the other currently values and that you don't see `Unexpected token in JSON at position ...` before attempting to restart by clicking on `Apply & restart`.

**Note**: This is a copy of the original docker docs at https://docs.docker.com/config/daemon/ipv6/ which apparently are not correct. However experimental is set to true which the ip6tables feature needs. Thus it will not get included into the official docs. However it is needed to make it work in our testing.

### How to run AIO on macOS?
On macOS, there is only one thing different in comparison to Linux: instead of using `--volume /var/run/docker.sock:/var/run/docker.sock:ro`, you need to use `--volume /var/run/docker.sock.raw:/var/run/docker.sock:ro` to run it after you installed [Docker Desktop](https://www.docker.com/products/docker-desktop/). Apart from that it should work and behave the same like on Linux.

Apart from that it should work and behave the same like on Linux.
Also, you may be interested in adjusting Nextcloud's Datadir to store the files on the host system. See [this documentation](https://github.com/nextcloud/all-in-one#how-to-change-the-default-location-of-nextclouds-datadir) on how to do it.
### How to run AIO on Windows?
On Windows, the following command should work in the command prompt after you installed [Docker Desktop](https://www.docker.com/products/docker-desktop/):
