abstract var enableAdditionalDnsQueryTypes: Boolean?

Controls whether additional DNS query types, e.g. HTTPS (DNS type 65) will be allowed besides the traditional A and AAAA queries when a request is being made via insecure DNS. Has no effect on Secure DNS which always allows additional types. Defaults to true.

abstract var enableBuiltInResolver: Boolean?

Whether the built-in host resolver is used in preference to getaddrinfo. When enabled, the built-in resolver will attempt to use the system's DNS settings to do DNS lookups itself. Enabled by default on macOS, disabled by default on Windows and Linux.

abstract var secureDnsMode: ConfigureHostResolverOptionsSecureDnsMode?

Can be 'off', 'automatic' or 'secure'. Configures the DNS-over-HTTP mode. When 'off', no DoH lookups will be performed. When 'automatic', DoH lookups will be performed first if DoH is available, and insecure DNS lookups will be performed as a fallback. When 'secure', only DoH lookups will be performed. Defaults to 'automatic'.

abstract var secureDnsServers: ReadonlyArray<String>?

A list of DNS-over-HTTP server templates. See RFC8484 § 3 for details on the template format. Most servers support the POST method; the template for such servers is simply a URI. Note that for some DNS providers, the resolver will automatically upgrade to DoH unless DoH is explicitly disabled, even if there are no DoH servers provided in this list.
