+#### Node
+
+`node` value determines which Technitium cluster node the statistics are returned for. Specifying a value of `cluster` returns aggregrate stats for all nodes in the cluster. Specify a node domain name to return specific node stats, no value returns stats for the node against which the API is executed.
+
 #### Range
 
 `range` value determines how far back of statistics to pull data for. The value comes directly from Technitium API documentation found [here](https://github.com/TechnitiumSoftware/DnsServer/blob/master/APIDOCS.md#dashboard-api-calls), defined as `"type"`. The value can be one of: `LastHour`, `LastDay`, `LastWeek`, `LastMonth`, `LastYear`.
