+# Disable IPV6
+
+Currently, IPV6 has entered thousands of households. However, in some cases, IPV6 addresses need to be disabled. Smartdns supports the following ways to disable IPV6 addresses.
+
+1. Method 1: Completely Disable IPV6
+
+    ```shell
+    force-AAAA-SOA yes
+    ```
+
+1. Method 2: Disable IPV6 of Specific Domain Name
+
+    ```shell
+    address /example.com/#6
+    ```
+
+## Disable Other Query Requests
+
+Smartdns supports disabling other query requests, and the corresponding parameter is `force-qtype-SOA`.
+
+```shell
+force-qtype-SOA 28
+```
+
+After force-qtype-SOA parameter is the type of DNS. The specific types can be queried from the IANA Explanation.
+
+## Additional Notes
+
+Smartdns has the ability to automatically detect IPV6 environment. If the network environment does not support IPV6, the IPV6-related optimization functions will be automatically disabled.
