This object identifies the host of a UAC controller instance; the MIB's own DESCRIPTION text duplicates the wording used for nsUACControlerName, but the object name and its position in the table identify it as the controller's host address. An admin uses this value to know which network host each configured UAC controller's connection status corresponds to. For example (illustrative), nsUACControlerHost might contain a hostname such as uac-ctrl.example.com identifying where that controller instance runs.
