A Dynamic Management Information Base (MIB) is a MIB that is flexible and allows for the addition or removal of attributes or variables without modifying the structure or the schema of the MIB. A dynamic MIB is designed to be easily adaptable to changing network environments and needs, and enables administrators to manage different types of network devices, services, and applications. It also allows for automated provisioning of devices and services, simplifying the network management process. Dynamic MIBs are often used in conjunction with Simple Network Management Protocol (SNMP) to monitor and manage network performance, troubleshoot issues, and improve network security.
