-When enabled, `local` DNS server will resolve DNS by dialing itself whenever possible.
-
-Specifically, it disables following behaviors which was added as features in sing-box 1.13.0:
-
-* On Apple platforms: Use `libresolv` for resolution, as it is the only one that works properly with NetworkExtension
-  that overrides DNS servers (DHCP is also possible but is not considered).
-* On Linux: Resolve through `systemd-resolvd`'s DBus interface when available.
-
-As a sole exception, it cannot disable the following behavior:
-
-In the Android graphical client, the `local` DNS server will always resolve DNS through the platform interface,
-as there is no other way to obtain upstream DNS servers. 
-
-On devices running Android versions lower than 10, this interface can only resolve IP queries.
