云数据库 Redis® 多可用区实例和单可用区实例的访问方式一致，均提供一个内网 IPv4 地址，方便客户端访问数据库实例。
内网 IPv4 地址
一个云数据库 Redis® 实例，主从节点部署在不同的可用区，跨可用区部署。同一私有网络下可以创建不同可用区的子网，不同可用区的子网默认内网互通。系统依据实例所选择的私有网络为其分配一个内网 IPv4 地址，在整个地域下客户端都可以通过该内网 IPv4 地址访问实例。
内网 IPv4 地址可以屏蔽 Redis 服务的故障切换，在 Redis 服务节点发生故障引发主从切换后，Redis 服务将在后台自动更新内网 IPv4 地址关联的后端服务进程，业务无需更换内网 IPv4 地址。
查看实例内网 IP 地址
登录 Redis 控制台，在实例列表的网络列，可查看到为实例分配的内网 IPv4地址。
在 实例列表，单击实例 ID 进入管理页面，在实例详情页的网络信息区域，可以查看到实例的内网 IPv4地址。
访问多可用区实例
多语言 SDK，访问 Redis 实例。具体操作，请参见 连接 Redis 实例。
在多可用区部署的情况下，为了降低业务访问 Redis 服务的时延，云数据库 Redis® 提供就近访问的能力。
