如果你的集群启用了 IPv4/IPv6 双协议栈网络，则可以使用 IPv4 或 IPv6 地址来创建 {{< glossary_tooltip text="Services" term_id="service" >}}。你可以通过设置服务的 `.spec.ipFamily` 字段来选择服务的集群 IP 的地址族。你只能在创建新服务时设置该字段。`.spec.ipFamily` 字段的设置是可选的，并且仅当你计划在集群上启用 IPv4 和 IPv6 的 {{< glossary_tooltip text="Services" term_id="service" >}} 和 {{< glossary_tooltip text="Ingresses" term_id="ingress" >}}。对于[出口](#出口流量)流量，该字段的配置不是必须的。
