|
### Fields
|
|
|
|
| Key | Format |
|
|
|----------|--------------------------------|
|
|
| `server` | List of [DNS Server](./server) |
|
|
| `rules` | List of [DNS Rule](./rule) |
|
|
|
|
#### 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.
|
|
|
|
#### 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.
