   Parameter	Description
   Home Subnet	Indicates the subnet to which the zone belongs.
   Sub-domain Name	Indicates the sub-domain name of the zone. This function must be used together with the DNS function in the subnet.
   DNS Policy	Indicates the DNS policy of the zone. Possible options are as follows: Round robin If clients access services using domain names, nodes are selected to process service requests of clients based on the sequence recorded in the cache. Node connections If clients access services using domains names, nodes with the fewest connections are selected to process service requests of clients. CPU usage If clients access services using domains names, nodes with the lowest CPU usage are selected to process service requests of clients. Node throughput If clients access services using domains names, nodes with the lowest throughput are selected to process service requests of clients.
   DNS Service	Indicates whether to enable the DNS service.
   IP Address Failover	Indicates whether to enable IP address failover. After this parameter is enabled, when a node is faulty, its IP address can be automatically allocated to another normal node. Therefore, clients can continue to access the storage system using this IP address.
