1.  Introduction

   The following sections describe the allocation guidelines associated
   with the specified fields within the Internet Group Management
   Protocol (IGMP) [I-D.ietf-pim-3376bis] and the Multicast Listener
   Discovery (MLD) [I-D.ietf-pim-3810bis] headers.  Some of these
   registries were created previously, while others are created by this
   document.

   This document obsoletes [RFC3228] and updates [RFC4443].

   The capitalized key words "MUST", "MUST NOT", "REQUIRED", "SHALL",
   "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and
   "OPTIONAL" in this document are to be interpreted as described in
   [RFC2119].

2.  IANA Considerations

   The registration procedures used in this document are defined in
   [RFC8126].

2.1.  Type and Code Fields

Internet-Draft                  IGMP IANA                   October 2023


2.1.1.  Internet Group Management Protocol

   The IGMP header contains the following fields that carry values
   assigned from IANA-managed name spaces: Type and Code.  Code field
   values are defined relative to a specific Type value.

   [RFC3228] created an IANA registry for the IGMP Type field.  This
   document updates that registry in two ways:

      The registration procedure is changed to Standards Action.

      The reference for the registry is changed to this document.

   [RFC3228] created an IANA registry for Code values for existing IGMP
   Type fields.  The registration procedure for the existing registries
   is changed to Standards Action.  The policy for assigning Code values
   for new IGMP Types MUST be defined in the document defining the new
   Type value.

2.1.2.  Multicast Listener Discovery

   As with IGMP, the MLD header also contains Type and Code fields.
   Assignment of those fields within the MLD header is defined in
   [RFC4443].

2.2.  Query Message Flags

   The IANA is requested to create a single registry for the bits in the
   Flags field of the Multicast Listener Query Message
   [I-D.ietf-pim-3810bis] and the IGMPv3 Query Message
   [I-D.ietf-pim-3376bis].  The format for the registry is:

      +----------+------------+-------------+-----------+
      | Resv Bit | Short Name | Description | Reference |
      +----------+------------+-------------+-----------+
      | 0        |            |             |           |
      | 1        |            |             |           |
      | 2        |            |             |           |
      | 3        |            |             |           |
      +----------+------------+-------------+-----------+

   The assignment of new bit flags within the Flags field requires
   Standards Action.

2.3.  Report Message Flags

   The IANA is requested to create a single registry for the bits in the
   Flags field of the Multicast Listener Report Message and the IGMPv3
   Report Message.  The format for the registry is:

      +-----------+------------+-------------+-----------+
      | Flags Bit | Short Name | Description | Reference |
      +-----------+------------+-------------+-----------+
      | 0         |            |             |           |
      | 1         |            |             |           |
      | 2         |            |             |           |
      | 3         |            |             |           |
      | 4         |            |             |           |
      | 5         |            |             |           |
      | 6         |            |             |           |
      | 7         |            |             |           |
      | 8         |            |             |           |
      | 9         |            |             |           |
      | 10        |            |             |           |
      | 11        |            |             |           |
      | 12        |            |             |           |
      | 13        |            |             |           |
      | 14        |            |             |           |
      | 15        |            |             |           |
      +-----------+------------+-------------+-----------+

   The assignment of new bit flags within the Flags field require
   Standards Action.

3.  Security Considerations

   This document only defines IANA registy actions and there are no
   associated security issues.
