Ori Industries JHU/APL This document updates both the specification of the ipn URI scheme previously defined in [RFC7116] and the rules for encoding of these URIs when used as an Endpoint Identifier (EID) in Bundle Protocol Version 7 (BPv7) as defined in [RFC9171]. These updates update and clarify the structure and behavior of the ipn URI scheme, define encodings of ipn scheme URIs, and establish the registries necessary to manage this scheme.
