works fine so just make sure to reflect this correctly in the document.

 You can use the DNSCrypt-Proxy as a full-featured standalone DNS instead of Unbound or Dnsmasq.
 This setup has the advantage that you do not need a forwarder solution for encrypting DNS requests

 To do so go to **Services->Unbound DNS->General** and uncheck *Enable*. If you are using Dnsmasq
 go to **Services->Dnsmasq DNS->Settings** and uncheck *Enable*. Now change to **Services->DNSCrypt-Proxy->Configuration**
-and add your Local LAN IP address to the *Listen Address* field, e.g. 192.168.2.1:53.

-For IPv6 with dynamic prefixes you can work around this with ::1:53 as *Listen Address* and add

-Optionally you can set :53 to listen on all addresses like the default behaviour in Unbound.
+and add the *Listen Address* 0.0.0.0:53 as well as [::]:53 for the service to be considered as

 Now you can go on with your configuration task, like choosing which servers to use, privacy policy or caching.
 Also cloaking (overrides) or DNSBL can be used without any workarounds.
