configureHostResolver

Configures host resolution (DNS and DNS-over-HTTPS). By default, the following resolvers will be used, in order:

• DNS-over-HTTPS, if the DNS provider supports it, then

• the built-in resolver (enabled on macOS only by default), then

• the system's resolver (e.g. getaddrinfo).

This can be configured to either restrict usage of non-encrypted DNS (secureDnsMode: "secure"), or disable DNS-over-HTTPS (secureDnsMode: "off"). It is also possible to enable or disable the built-in resolver.

To disable insecure DNS, you can specify a secureDnsMode of "secure". If you do so, you should make sure to provide a list of DNS-over-HTTPS servers to use, in case the user's DNS configuration does not include a provider that supports DoH.

This API must be called after the ready event is emitted.
