Private OID range(s) ?

[Nick Milas <nick@eurobjects.com>]

Hello,

I was wondering whether there exists - officially or unofficially - a 
range of private OIDs which can be used internally (privately) in an 
organization, and is not allowed for schema distribution; something like 
private network IP address ranges (10.0.0.0/8, etc.)
The existence of such private OIDs would allow organizations to avoid 
registering their own OID branch, since the "private" OID range would 
guarrantee that these OIDs can be used internally by the organization 
safely and would not be included in a new schema distribution; thus, 
conflicts can be excluded. Any organization which would be using such a 
"private OID range", should not be allowed to make the associated LDAP 
attributes publicly available (not even searchable) in its Directory 
interations.
Secondarily, the above would also serve as an "example" range of OIDs 
which could be used for communication of schema drafts.
I haven't come across something like this until now.

Thanks,
Nick
