Registering an OID

Each object class or attribute type must be assigned a unique name and Object Identifier (OID). Generally, one OID is sufficient to meet all of your schema needs by adding another level of hierarchy to create new branches, or OID arcs. An OID arc is an OID that has been reserved for use as a container for defining additional OIDs.

You can obtain an OID from the IANA home page at http://iana.org. Other organizations that issue OIDs are ANSI (for US organizations), and BSI (for UK organizations).

Note: IANA's term for OIDs is enterprise numbers, as they are used primarily for Simple Network Management Protocol (SNMP).
