### Structure

{
|
|
"dns": {
|
|
"servers": [],
|
|
"rules": [],
|
|
"final": "",
|
|

}

|
```
|
|
|
|
### Fields
|
|
|
|
| Key | Format |
|
|
|----------|---------------------------------|
|
|
| `server` | List of [DNS Server](./server/) |
|
|
| `rules` | List of [DNS Rule](./rule/) |
|
|
| `fakeip` | [FakeIP](./fakeip/) |
|
|
|
|
#### final
|
|
|
|
Default dns server tag.
|
|
|
|
The first server will be used if empty.
|
|
|
|
#### strategy
|
|
|
|
Default domain strategy for resolving the domain names.
|
|
|
|
One of `prefer_ipv4` `prefer_ipv6` `ipv4_only` `ipv6_only`.
|
|
|
|
Take no effect if `server.strategy` is set.
|
|
|
|
#### disable_cache
|
|
|
|
Disable dns cache.
|
|
|
|
#### disable_expire
|
|
|
|
Disable dns cache expire.
|
|
|
|
#### independent_cache
|
|
|
|
Make each DNS server's cache independent for special purposes. If enabled, will slightly degrade performance.
|
|
|
|
#### reverse_mapping
|
|
|
|
Stores a reverse mapping of IP addresses after responding to a DNS query in order to provide domain names when routing.
|
|
|
|
Since this process relies on the act of resolving domain names by an application before making a request, it can be
|
|
problematic in environments such as macOS, where DNS is proxied and cached by the system.
|
|
|
|
#### client_subnet
|
|
|
|
!!! question "Since sing-box 1.9.0"
|
|
|
|
Append a `edns0-subnet` OPT extra record with the specified IP prefix to every query by default.
|
|
|
|
If value is an IP address instead of prefix, `/32` or `/128` will be appended automatically.
|
|
|
|
Can be overrides by `servers.[].client_subnet` or `rules.[].client_subnet`.
