This informational document describes a new Uniform Resource Name (URN) namespace for hardware device identifiers. URNs can be easily passed along in an application that needs the information, as it fits in protocols mechanisms that are designed to carry URNs. This URNs usage is  an alternative to Universally Unique IDentifiers (UUIDs) for cases where it is important that the identifiers are as simple as possible and where additional requirements on stable storage, real-time clocks, and identifier length can be prohibitive. 

The document is short and clear. There is no significant impact form an operational or manageability point of view. It is useful for network operators to read Section 4 (DEV URN Subtypes) which can provide useful information for operational actions or troubleshooting. 

This document is READY from an OPS-DIR perspective.
