Experimental/private branch for OID numbers in LDAP Schemas?
Attributes or object classes in LDAP schemas are identified through a unique number called OID. Moreover OIDs are also used in the SNMP protocol. Everyone can apply for an enterprise number by the IANA and then define his own subnumbers. But the processing of the application can last up to 30 days.
Does anyone know if there is a "test" branch of OID numbers that could be used for experimental purposes while waiting for an official enterprise number?
Answer
Apparently the OID branch 2.25 can be used with UUIDs without registration. The detailled explanation can be found here: http://www.oid-info.com/get/2.25 and there is also a link to an UUID generator.
=> I think it's good solution for unregistered OIDs. Simply generate one such OID with the UUID-Generator. You will get something like 2.25.178307330326388478625988293987992454427 and can then simply make your own subnumbers by adding .1, .2, ... at the end.
There is also the possibility to register such an 2.25 OID, but a human intervention is still needed and uniqueness isn't totally garanteed as it is still possible (although unlikely) that someone else uses the same OID as unregistered OID. For registered OIDs I would still prefer the registration of a private entreprise number by the IANA.
Here is also a list of how to get an OID assigned: http://www.oid-info.com/faq.htm#10. But the main answers are already listed here.
