public static enum Cluster.DnsLookupFamily extends java.lang.Enum<Cluster.DnsLookupFamily> implements com.google.protobuf.ProtocolMessageEnum
When V4_ONLY is selected, the DNS resolver will only perform a lookup for addresses in the IPv4 family. If V6_ONLY is selected, the DNS resolver will only perform a lookup for addresses in the IPv6 family. If AUTO is specified, the DNS resolver will first perform a lookup for addresses in the IPv6 family and fallback to a lookup for addresses in the IPv4 family. This is semantically equivalent to a non-existent V6_PREFERRED option. AUTO is a legacy name that is more opaque than necessary and will be deprecated in favor of V6_PREFERRED in a future major version of the API. If V4_PREFERRED is specified, the DNS resolver will first perform a lookup for addresses in the IPv4 family and fallback to a lookup for addresses in the IPv6 family. i.e., the callback target will only get v6 addresses if there were NO v4 addresses to return. If ALL is specified, the DNS resolver will perform a lookup for both IPv4 and IPv6 families, and return all resolved addresses. When this is used, Happy Eyeballs will be enabled for upstream connections. Refer to :ref:`Happy Eyeballs Support <arch_overview_happy_eyeballs>` for more information. For cluster types other than :ref:`STRICT_DNS<envoy_v3_api_enum_value_config.cluster.v3.Cluster.DiscoveryType.STRICT_DNS>` and :ref:`LOGICAL_DNS<envoy_v3_api_enum_value_config.cluster.v3.Cluster.DiscoveryType.LOGICAL_DNS>`, this setting is ignored. [#next-major-version: deprecate AUTO in favor of a V6_PREFERRED option.]
