+### 使用 IPv6 优选
+
+从原理上来看，本服务通过读取`config/result_v6.csv`文件获取`IPv6`地址，因此您可以在支持
+`IPv6`的服务器上运行`IP`选优功能来获得`IPv6`地址。获取到的接入地址列表只需写入
+`config/result_v6.csv`文件中，相比在`Docker`容器中运行`IP`选优功能，此方法更为简便。
+
+如果您需要在`Docker`容器中运行`IP`选优功能，可以使用`docker-compose_ipv6.yaml`
+文件来让`Docker`镜像支持`IPv6`。在运行前，请确保您的服务器支持`IPv6`，并在`Docker`服务的
+`/etc/docker/daemon.json`中添加以下内容，并重启`Docker`服务：
+
+```json
+{
+  "experimental": true,
+  "ip6tables": true,
+  "ipv6": true,
+  "fixed-cidr-v6": "2001:db8:1::/64"
+}
+```
+
+若您在先前已经运行过`Docker`服务，在运行之前，请先停止之前的服务：
+
+```bash
+docker-compose down
+```
+
+然后，您可以通过以下命令来运行`Docker`服务：
+
+```bash
+docker-compose -f docker-compose_ipv6.yaml up -d
+```

+### Using IPv6 Preference
+
+In principle, this service obtains IPv6 addresses by reading
+the `config/result_v6.csv` file. Therefore, you can run the IP preference
+function on a server that supports IPv6 to obtain IPv6 addresses. The list of
+obtained access addresses only needs to be written into
+the `config/result_v6.csv` file. Compared to running the IP preference function
+in a Docker container, this method is more straightforward.
+
+If you need to run the IP preference function in a Docker container, you can use
+the `docker-compose_ipv6.yaml` file to make the Docker image support IPv6.
+Before running, please ensure that your server supports IPv6 and add the
+following content to /etc/docker/daemon.json in the Docker service (remember to
+restart the Docker service):
+
+```json
+{
+  "experimental": true,
+  "ip6tables": true,
+  "ipv6": true,
+  "fixed-cidr-v6": "2001:db8:1::/64"
+}
+```
+
+If you have previously run the Docker service, please stop the previous service
+before running:
+
+```bash
+docker-compose down
+```
+
+Then, you can run the Docker service with the following command:
+
+```bash
+docker-compose -f docker-compose_ipv6.yaml up -d
+```
