I received a IANA Private Enterprise Number, 10569, but now I am not sure how to construct a proper OID. Would I start with 1.3.6.1.4.1.10569 as the top of my "personal" tree? And then build my hierarchy below that? For example, 1.3.6.1.4.1.10569.1 Item 1 1.3.6.1.4.1.10569.1.1 Item 1, Sub-Item 1 1.3.6.1.4.1.10569.1.2 Item 1, Sub-Item 2 1.3.6.1.4.1.10569.2 Item 2 1.3.6.1.4.1.10569.3 Item 3 Thanks, Chuck Coker
