+### Are you in the right namespace for the service?
+
+DNS queries that don't specify a namespace are limited to the pod's 
+namespace. 
+
+If the namespace of the pod and service differ, the DNS query must include 
+the namespace of the service.
+
+This query is limited to the pod's namespace:
+```shell
+kubectl exec -i -t dnsutils -- nslookup <service-name>
+```
+-->
+### 你的服务在正确的命名空间中吗？
+
+未指定命名空间的 DNS 查询仅作用于 pod 所在的命名空间。
+
+如果 pod 和服务的命名空间不相同，则 DNS 查询必须指定服务所在的命名空间。
+
+该查询仅限于 pod 所在的名称空间：
+```shell
+kubectl exec -i -t dnsutils -- nslookup <service-name>
+```
+
+<!--
+This query specifies the namespace:
+```shell
+kubectl exec -i -t dnsutils -- nslookup <service-name>.<namespace>
