This is a direction to [IANA] concerning the creation and management of the IANA IPv4 Special Purpose Address Registry. The registry will be used for recording IETF protocol assignments from 192.0.0.0/24 and any other address prefixes allocated to the registry in the future, as described in Section 3.
这是向[IANA]发出的有关创建和管理IANA IPv4专用地址注册表的指示。注册表将用于记录192.0.0.0/24中的IETF协议分配以及将来分配给注册表的任何其他地址前缀，如第3节所述。
[RFC5735] records the assignment of an IPv4 address prefix to IANA for IETF protocol assignments.
[RFC5735]记录将IPv4地址前缀分配给IANA以用于IETF协议分配。
192.0.0.0/24 - This block is reserved for IETF protocol assignments.
192.0.0.0/24-此块保留用于IETF协议分配。
This address allocation to IANA is intended to support IETF protocol assignments. A more general view of the roles of IANA with respect to address allocation functions is documented in [RFC2860]:
IANA的地址分配旨在支持IETF协议分配。[RFC2860]中记录了IANA在地址分配功能方面的作用的更一般视图：
4.3. [...] Note that [...] (b) assignments of specialised address blocks (such as multicast or anycast blocks), and (c) experimental assignments are not considered to be policy issues, and shall remain subject to the provisions of this Section 4. (For purposes of this MOU, the term "assignments" includes allocations.)
4.3. […]请注意[…]（b）专用地址块（如多播或选播块）的分配，以及（c）实验性分配不被视为政策问题，应遵守本第4节的规定。（就本谅解备忘录而言，“转让”一词包括分配。）
The reference to Section 4 here is to the general technical work for the IANA as described in [RFC2860]:
此处参考第4节是指[RFC2860]中所述IANA的一般技术工作：
4.1. The IANA will assign and register Internet protocol parameters only as directed by the criteria and procedures specified in RFCs, including Proposed, Draft, and full Internet Standards and Best Current Practice documents, and any other RFC that calls for IANA assignment.
4.1. IANA将仅按照RFC中规定的标准和程序分配和注册互联网协议参数，包括提议的、草案的和完整的互联网标准和最佳现行实践文件，以及要求IANA分配的任何其他RFC。
This document directs IANA to designate special purpose address blocks in compliance with [RFC2860].
本文件指示IANA根据[RFC2860]指定专用地址块。
This document directs IANA to open an IPv4 Special Purpose Address Registry for the management of these IANA-designated address blocks. Special Purpose registrations to be made from this registry include addresses for IETF protocol assignments and other special purpose cases, as documented in IESG-reviewed RFCs, according to the provisions described in Section 4.1 of [RFC2860].
本文档指导IANA打开IPv4专用地址注册表，以管理这些IANA指定的地址块。根据[RFC2860]第4.1节所述规定，从该注册中心进行的特殊用途注册包括IETF协议分配地址和其他特殊用途案例，如IESG审查的RFC中所述。
IANA maintains an "IANA IPv4 Special Purpose Address Registry". The registry records current IANA address designations from the IANA-managed IPv4 Special Purpose address pool.
IANA维护一个“IANA IPv4专用地址注册表”。注册表记录来自IANA管理的IPv4专用地址池的当前IANA地址指定。
This recommendation concerns the management of the address pool used for IETF protocol assignments as documented in [RFC5735] -- namely, 192.0.0.0/24. Following the policies outlined in [RFC5226], further assignments of address space to IANA for subsequent designation of address prefixes for the purposes listed here shall be undertaken only through an IETF Review action.
本建议涉及[RFC5735]中记录的用于IETF协议分配的地址池的管理，即192.0.0.0/24。按照[RFC5226]中概述的政策，仅可通过IETF审查行动，向IANA进一步分配地址空间，以便随后指定用于此处所列目的的地址前缀。
IANA may make Special Purpose address designations to support testing or experimental usage activities initiated by the IETF, or for specialised use of a designated address block in a context (e.g., anycast) associated with an Internet Standards Track protocol. All such address designations must be documented in the "IANA Considerations" section of an IESG-reviewed RFC.
IANA可指定专用地址，以支持IETF发起的测试或实验性使用活动，或在与互联网标准跟踪协议相关的上下文（例如，选播）中专门使用指定地址块。所有此类地址指定必须记录在IESG审查RFC的“IANA注意事项”部分。
The IANA IPv4 Special Purpose Address Registry records, for all current address designations undertaken by IANA:
IANA IPv4专用地址注册表记录IANA进行的所有当前地址指定：
1. The designated address prefix.
1. 指定的地址前缀。
2. The RFC that called for the IANA address designation.
2. 要求IANA地址指定的RFC。
3. The date the designation was made.
3. 指定的日期。
4. The date the use designation is to be terminated (if specified as a limited-use designation).
4. 终止使用标识的日期（如果指定为限制使用标识）。
5. The nature of the purpose of the designated address (e.g., unicast experiment or protocol service anycast).
5. 指定地址用途的性质（例如，单播实验或协议服务选播）。
6. For experimental unicast applications and otherwise as appropriate, the registry will also identify the entity and related contact details to whom the address designation has been made.
6. 对于实验性单播应用程序和其他适当的应用程序，注册中心还将确定地址指定对象的实体和相关联系方式。
7. The registry will also note, for each designation, the intended routing scope of the address, indicating whether the address is intended to be routable only in scoped, local, or private contexts, or whether the address prefix is intended to be routed globally.
7. 注册表还将注意到，对于每个指定，地址的预期路由范围，指示地址是否仅在范围、本地或私有上下文中可路由，或者地址前缀是否打算全局路由。
8. The date in the IANA registry is the date of the IANA action, i.e., the day IANA records the allocation.
8. IANA注册表中的日期是IANA行动的日期，即IANA记录分配的日期。
The IANA registry notes, as a general comment, that address prefixes listed in the IPv4 Special Purpose Address Registry are not guaranteed routability in any particular local or global context.
IANA注册中心指出，作为一般性意见，IPv4专用地址注册中心中列出的地址前缀在任何特定的本地或全局上下文中都不能保证可路由性。
IANA will not maintain further sub-registries for any IPv4 Special Purpose address block designated according to this direction.
IANA不会为根据本指令指定的任何IPv4专用地址块维护进一步的子注册表。
Security of the Internet's routing system relies on the ability to authenticate an assertion of unique control of an address block. Measures to authenticate such assertions rely on validation that the address block forms part of an existing allocated address block, and that there is a trustable and unique reference in the IANA address registries.
Internet路由系统的安全性依赖于对地址块的唯一控制断言进行身份验证的能力。验证此类断言的措施依赖于验证地址块是否构成现有已分配地址块的一部分，以及IANA地址注册表中是否存在可信任且唯一的引用。
This registry is intended to provide an authoritative source of information regarding the currency and intended purpose of IPv4 Special Purpose address blocks that are designated from the IANA-administered IPv4 Special Purpose address pool. This is a small step towards the creation of a comprehensive registry framework that can be used as a trust point for commencing a chain of address validation. Consideration should be given to the use of file signatures and associated certificate mechanisms to allow applications to confirm that the registry contents are current, and that they have been published by the IANA.
此注册表旨在提供有关从IANA管理的IPv4专用地址池中指定的IPv4专用地址块的货币和预期用途的权威信息源。这是创建一个全面的注册表框架的一小步，该框架可用作启动地址链验证的信任点。应考虑使用文件签名和相关证书机制，以允许应用程序确认注册表内容是最新的，并且已由IANA发布。
