Fields

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.
