PenOid 1.0.3

PenOid

Support for interacting with Private Enterprise Number (PEN) object identifiers (OIDs) assigned by IANA.

About

The Internet Assigned Numbers Authority (IANA) assigns Private Enterprise Numbers (PENs) to organizations and individuals on a first-come, first-served basis. Full details on obtaining a PEN can be found at the IANA web site along with a list of current registrations.

The prefix within the OID hierarchy for all PEN assignments is 1.3.6.1.4.1

Example Usage

Assuming a PEN value of 32473 from IANA, you can interact with the PenOid class by creating a new instance:

var penOid = new PenOid(32473);

Calling ToString() on the above instance will yield 1.3.6.1.4.1.32473.

You can create a new hierarchy beneath the 32473 tree by appending the new identifier to the PenOid instance:

penOid.AppendComponent(1);

Calling ToString() on the above instance will now yield: 1.3.6.1.4.1.32473.1.

You can also create a new PenOid instance by providing a full OID in dotted notation:

var penOid = new PenOid("1.3.6.1.4.1.32473.1.42");

IANA Registry

This package provides the PenRegistryProvider class to download and parse the IANA-maintained PEN registry:

var registryProvider = new PenRegistryProvider();
var registryContents = registryProvider.FromIana();

Assuming a successful web response, registryContents now contains a list of PenOidWithMetadata objects representing the IANA-maintained PEN registry. Each object stores the assigned PEN, registrant name, contact person, and contact detail for a specific PEN in the registry.
