 Private Enterprise Number (PEN) practices and registration procedures
                        draft-liang-iana-pen-00

Abstract

   Private Enterprise Numbers (PENs), are assigned as part of the
   technical protocol parameters and are frequently used in the
   management of network connected equipment or software via SNMP-based
   network management systems, LDAP, DIAMETER or GSS-API.  This document
   discusses what a Private Enterprise Number (PEN) is, common uses and
   registration procedures.  The registration procedures include
   instructions for obtaining a new Private Enterprise Number,
   modification to existing numbers and removal.

Internet-Draft                  PEN v.0.2                     March 2012


1.  Introduction

   A Private Enterprise Number (PEN) is a non-negative integer that can
   be used to reference an organization ("enterprise") in protocols that
   require numeric values instead of a human readable organization name.

   Currently, the assignment procedures for assignment of new PENs and
   the modification of existing PENs is not clearly documented.  Private
   Enterprise Numbers are referenced in RFCs [RFC1157] [RFC1213] and
   [RFC2578].  These documents mostly define Simple Network Management
   Protocol (SNMP), Management Information Base (MIB), and Structure of
   Management Information (SMI).  However, none of the above mentioned
   RFCs clearly describe PENs and define the registration procedures.

   Additionally, updates to existing Private Enterprise Numbers can also
   be problematic resulting from the lack of clear registration
   requirements.  Historical assignments that pre-exist ICANN's
   management of the registry, contains inaccurate information.  As
   result of that, ICANN/IANA has no reliable records of the historical
   registrations to verify new information against the original
   requests.  Furthermore, modification requests can be hardly validated
   in cases like companies change names and/or legal ownerships, a
   product was sold to another company, email addresses of existing
   assignments were not coming from the original companies, etc.

   This purpose of this document is to describe the basics of PENs, how
   they are most commonly used and define the registration and update
   procedures.


2.  Example of use for Private Enterprise Numbers

   PENs, are frequently embedded in OIDs (Object Identifiers) , which
   are often used in Simple Network Management Protocol (SNMP)
   Management Information Base (MIB) configurations but are also
   commonly used in a number of other protocols.  These include:

   Distinguished Names and other components in X.509 certificates;

   Various schema elements in X.500/LDAP directories;

   GSS-API

   extensions to DIAMETER

   PA-TNC [RFC5792] and PB-TNC [RFC5793]

   Various healthcare related standards, including HL7.

3.  Who can get a Private Enterprise Number?

   Private Enterprise Numbers (PENs) are assigned through First Come
   First Served registration policy as described in [RFC5226].  A new
   request can be submitted to IANA by individuals or organizations for
   obtaining a unique value with a little required information that
   includes the organization name (or the name of an individual),
   contact name, and e-mail address.  In some cases, users submit a
   program name, product, project, and random abbreviation as the
   organization name to apply for a new registration.  However this
   should be discouraged since the program name is not and should not be
   considered as the name of the Registrant (Company/Organization) Name
   as described in Section 7 below.

   In other instances, applicants insist that new requests are
   subsidiaries of some groups but the subsidiaries are completely
   independent of the parent groups.  The subsidiaries are located in
   different locations and countries from the parent companies and such
   the subsidiaries cannot use existing allocations.  However, this does
   not contribute to new allocations as the global companies shall be
   able to create sub-trees and to allocate the sub-numbers globally.
   IANA does not further allocate new numbers to companies that are
   subsidiaries of existing registrations.

   Further, joint ventures of business enterprises may request new
   allocations if the joint ventures are considered new legal bodies.
   Open resource forums may request new allocations under the
   registration requirement as describe in Section 7 (IANA
   Considerations).  Individuals may requests new allocations under the
   registration requirement as describe in Section 7 (IANA
   Considerations).


4.  Other useful things to know

   As some examples documented on Wikipedia, the most common OIDs seen
   "in the wild" usually belong to the private enterprise numbers
   allocated by IANA under the 1.3.6.1.4.1
   (iso.org.dod.internet.private.enterprise) arc.  Increasingly used
   form of OID is in the area of health care and public health
   informatics in the United States.  Health Level Seven (HL7), a
   standards-developing organization in the area of electronic health
   care data exchange, is an assigning authority at the
   2.16.840.1.113883 (joint-iso-itu-t.country.us.organization.hl7) node.

   Additional sub-trees of the existing arc
   iso.org.dod.internet.private.enterprise.<PEN> can be created by an
   administrator of the arc when the Registrant (Company) needs

Internet-Draft                  PEN v.0.2                     March 2012


   additional OIDs.  In such cases there is no need to request multiple
   PENs.  Note that IANA does not manage allocations of sub-OIDs below a
   iso.org.dod.internet.private.enterprise.<PEN> OID, so it doesn't need
   to be notified about suballocations.

   The owner of a Private Enterprise Number can append any number of
   numbers at the end (i.e. to perform its own sub-allocations).  For
   example, for LDAP, one can use:

   iso.org.dod.internet.private.enterprise.<PEN>.1 for LDAP Object
   Classes

   iso.org.dod.internet.private.enterprise.<PEN>.2 for LDAP attribute
   types

   iso.org.dod.internet.private.enterprise.<PEN>.3 for LDAP syntaxes

   A particular Object class can have OID:

   iso.org.dod.internet.private.enterprise.<PEN>.1.100

   iso.org.dod.internet.private.enterprise.<PEN>.1.200 for subsidiaries
   an/or divisions

   But in general any number of additional levels are permitted, for
   example:

   iso.org.dod.internet.private.enterprise.<PEN>.1.1 can be used as a
   parent OID for all email related object classes, and

   iso.org.dod.internet.private.enterprise.<PEN>.1.2 can be used for web
   related object classes, etc.


5.  Syntax for Private Enterprise Numbers

   Valid information for registrations are hereby normatively defined as
   follows:

   o MUST NOT begin or end with a hyphen

   o TBD: Subset of ASCII character (at least ALPHA, DIGIT and "-")

   o TBD: Special characters (At least Unicode letters?)

7.  IANA Considerations

   o New Private Enterprise Numbers:

   New Private Enterprise Numbers are assigned on a First Come First
   Served basis [RFC5226] and are assigned sequentially.  There is no
   opportunity to request a particular private enterprise number.  The
   requester can submit an online application form.  Information to be
   included:

   Registrant (Company/Organization) Name (REQUIRED)

   Registrant Postal Address (REQUIRED)

   Registrant Phone Number (Optional)

   Registrant Fax Number (OPTIONAL)

   Contact Name (REQUIRED)

   Contact E-mail Address (REQUIRED)

   Contact Postal Address (OPTIONAL)

   Contact Phone Number (OPTIONAL)

   Registrant (Company/Organization) Name: The name of the organization
   or individual responsible for the registration of Private Enterprise
   Number.  If the organization is a company, it should be the full
   legal name including "Inc.", "Ltd.", etc.

   Registrant Postal Address: The full postal address of the
   organization/individual requesting the PEN, including state/province,
   zip/postal code, country, etc.

   Registrant Phone: The main telephone number of the organization/
   individual requesting the PEN, including the country code.

   Registrant Fax Number: The facsimile number of the organization/
   individual responsible for the PEN, including the country code.

   Contact Name: The full name of the individual who will be responsible

Internet-Draft                  PEN v.0.2                     March 2012


   for the PEN on behalf of the company.

   Contact Postal Address: The full postal address of the individual
   responsible the PEN, including state/province, zip/postal code,
   country, etc.

   Contact Phone: The telephone number (with extension where
   appropriate) of the individual responsible for the PEN, including
   country code.

   Contact E-Mail: The e-mail address of the individual responsible for
   the PEN.  This e-mail address will be publicly available in the IANA
   PEN Registry.

   A single PEN is granted per organization.  IANA does not expect to
   allocate additional PENs to Registrants (Companies/Organizations)
   that have existing PEN records listed in the IANA PEN registry.

   o Modification of existing Private Enterprise Numbers:

   Registrant (Company/Organization) Name can never be changed.  However
   if the Company/Organization has been merged or acquired by another
   enterprise, the Registrant Name can be annotated in the registry with
   the new owner.  Note that such annotations would require emails from
   the both existing Contact and proposed Contact, and/or official
   letters from the existing owner (if applicable) to provide proofs of
   the changes.  If either the existing owner or Contact is obsoleted,
   an official letter from the proposed Registrant (Company/
   Organization) Name will be required.  Additional documentations will
   be required subject to the conditions of the changes of the numbers
   in questions.

   All information associated with existing PEN records, excluding the
   Registrant (Company/Organization) Name, shall be updated if the
   information is obsoleted.  (See the preceding section to update the
   Registrant (Company/Organization) Name.)  A request to update
   information associated with an existing PEN record shall be submitted
   to IANA.  Requests can only be fulfilled upon verification by IANA
   and/or subject matter experts.  Additional documentations will be
   required if it deems to be necessary to validate the request.

   A change to the Contact Name of existing PEN records can be made to
   IANA in case of personnel changes, change of employment,
   acquisitions, etc.  It would be ideal that new requests shall be
   completed by the existing Contacts for the PEN records.  E-mail
   verifications of the requested changes are required.  Alternatively,
   supplemental documentations and/or letters issued by the Company/
   Organization (Registrant Name) will be required if E-mail

Internet-Draft                  PEN v.0.2                     March 2012


   verifications cannot be fulfilled and if it deems to be necessary.

   Letters and documentations can be in forms of e-documents, PDF, fax
   however feasible to the applicants.  The documents can be supplied to
   IANA via an email message or in facsimile.

   Requests can only be fulfilled upon verification by IANA and/or
   subject matter experts.

   o Removal of Private Enterprise Numbers:

   A Contact Name can request to remove the corresponding PEN allocation
   if the resource is no longer in used or the resource does not meet
   the needs.  (In a case when the Contact Name is no longer with the
   Company/Organization, the Modification procedure described above MUST
   be used first.)  Such request does not happen often and regularly.

   Requests can only be fulfilled upon verification by IANA and/or
   subject matter experts.

   If the removal request is honoured, the entry is marked as
   "Unassigned" and can be reallocated by IANA later unless specified
   otherwise, i.e. by marking the entry as "Reserved".


8.  Security Considerations

   See the Security Considerations section in BCP 26 [RFC5226], and note
   that improper definition and application of IANA registration
   policies can introduce both interoperability and security issues.  It
   is critical that registration policies be considered carefully and
   separately for each registry.  Overly restrictive policies can result
   in the lack of registration of code points and parameters that need
   to be registered, while overly permissive policies can result in
   inappropriate registrations.  Striking the right balance is an
   important part of document development.
