With so many kinds of devices and so much data that can be accessed, there needed to be
a standard way to organize this plethora of data, so MIB to the rescue! A management
information base (MIB) is a collection of information that’s organized hierarchically and
can be accessed by protocols like SNMP. RFCs define some common public variables, but
most organizations define their own private branches along with basic SNMP standards.
Organizational IDs (OIDs) are laid out as a tree with different levels assigned by different
organizations, with top-level MIB OIDs belonging to various standards organizations.
