A management information base (MIB) is a hierarchical virtual database of network (or other entity) objects describing a device being monitored by a network management system (NMS). An MIB is used by Simple Network Management Protocol (SNMP) and remote monitoring 1 (RMON1).

The MIB database of objects is intended to reference a complete collection of management information on an entity, such as a computer network; however, it is often used to refer to a subset of the database and is often called an MIB module.
