OIDs (Object Identifiers) are coded as a series of integers separated by dots, where each integer represents a sub-identifier or node in the tree-like hierarchical structure of the OID. The first node or sub-identifier is usually a top-level identifier assigned by a standards organization, followed by subsequent nodes that provide more specific information about the object being identified. For example, the OID for the Simple Network Management Protocol (SNMP) is 1.3.6.1.6.1, where the first three nodes (1.3.6) correspond to the International Organization for Standardization (ISO), the International Telecommunication Union (ITU), and the Joint ISO/ITU-T (International Telecommunication Union-Telecommunications Standardization Sector) Networking Management Committee, respectively. The remaining nodes (1.6.1) represent more specific information about the SNMP protocol.
