Purpose
The purpose of this article is to explain Object Identifiers OIDs.
Introduction
Object Identifiers (OIDs) are used to provide a globally unambiguous, hierarchical name for every manageable object—such as an asset, SNMP routine, or monitored parameter. Each OID is a unique sequence of numbers defined according to international standards, ensuring consistency across systems and vendors. By using OIDs, Outpost24 can reliably reference assets, detection routines, and other identifiers without ambiguity, which improves interoperability, accuracy, and traceability in asset discovery and monitoring.
Syntax
An OID corresponds to a node in the OID hierarchy, which is defined using the ITU's OID standard, X.660. The root of the tree contains of three arcs: 0=ITU-T, 1=ISO, 2=joint-iso-itu-t
Each node in the tree is represented by a series of integers separated by periods, corresponding to the path from the root through the series of ancestor nodes, to the node. Thus, an OID denoting Outpost 24 appears as follows,
1.3.6.1.4.1.24255
and corresponds to the following path through the OID tree:
|
1 |
ISO |
|
1.3 |
Identified Organization |
|
1.3.6 |
United States Department of Defense (DOD)
|

1.3.6.1 |

Private |
|
1.3.6.1.4.1 |
IANA enterprise |
|
1.3.6.1.4.1.24255 |
Outpost24 AB |
A textual representation of the OID paths is also commonly seen; for example:
iso.organization.dod.internet.private.enterprise.Outpost24 AB
Each node in the tree is controlled by an assigning authority, which may define child nodes under the node and delegate assigning authority for the child nodes.
1.3.6.1.4.1.24255
{iso(1) org(3) dod(6) internet(1) private(4) enterprise(1) Outpost24 AB(24255)}
Outpost24 AB Registered Enterprise OID
The next position represents the node for SNMP Routines within Outpost24 for our products where 1=HIAB.
