+# 使用域名注册发现
+
+
+有些部署场景需要动态指定服务注册的地址，如docker bridge网络模式下要指定注册宿主机ip以实现外网通信。dubbo提供了两对启动阶段的系统属性，用于设置对外通信的ip、port地址  
+
+如果你想使用域名来将服务发布到注册中心上，需要使用`环境变量`遵循如下配置：  
+`DUBBO_IP_TO_REGISTRY` ：注册到注册中心的IP或主机域名  
+`DUBBO_PORT_TO_REGISTRY` ：注册到注册中心的port端口
+
+####注意：
+指定IP或主机域名不能使用以下几种情况：
+1. `0.0.0.0` 
+3. `127.*.*.*`
+3. `localhost`
+4. `环境变量为空或空字符串`
+
+消费端需要将发布到注册中心的主机域名配置到本地hosts中
