+## ONLYOFFICE Document Server ipv6 setup
+
+(Works and is supported only for Linux hosts)
+
+Docker does not currently provide ipv6 addresses to containers by default. This function is experimental now.
+
+To set up interaction via ipv6, you need to enable support for this feature in your Docker. For this you need:
+- create the `/etc/docker/daemon.json` file with the following content:
+
+```
+{
+"ipv6": true,
+"fixed-cidr-v6": "2001:db8:abc1::/64"
+}
+```
+- restart docker with the following command: `systemctl restart docker`
+
+After that, all running containers receive an ipv6 address and have an inet6 interface.
+
+You can check your default bridge network and see the field there
+`EnableIPv6=true`. A new ipv6 subnet will also be added.
+
+For more information, visit the official [Docker manual site](https://docs.docker.com/config/daemon/ipv6/)
