Adding 100.64.0.0/10 Prefixes to the IPv4 Locally-Served DNS Zones Registry

向IPv4本地服务DNS区域注册表添加100.64.0.0/10前缀

Abstract

摘要

RFC 6598 specifies that "Reverse DNS queries for Shared Address Space addresses [100.64.0.0/10] MUST NOT be forwarded to the global DNS infrastructure."

RFC 6598规定“共享地址空间地址[100.64.0.0/10]的反向DNS查询不得转发到全局DNS基础设施。”

This document formally directs IANA to add the associated zones to the "IPv4 Locally-Served DNS Zones Registry" to prevent such queries from accidentally leaking to the global DNS infrastructure.

本文档正式指示IANA将相关区域添加到“IPv4本地服务DNS区域注册表”,以防止此类查询意外泄漏到全局DNS基础设施。

1. Introduction
1. 介绍

[RFC6598] specifies that "Reverse DNS queries for Shared Address Space addresses [100.64.0.0/10] MUST NOT be forwarded to the global DNS infrastructure." [RFC6303] provides guidance on handling such queries.

[RFC6598]指定“共享地址空间地址[100.64.0.0/10]的反向DNS查询不得转发到全局DNS基础结构。”[RFC6303]提供了处理此类查询的指导。

This document directs the IANA to add the IPv4 reverse zones corresponding to 100.64.0.0/10, a netblock reserved in [RFC6598], to the "IPv4 Locally-Served DNS Zone Registry" established in [RFC6303].

本文档指示IANA将对应于[RFC6598]中保留的netblock 100.64.0.0/10的IPv4反向区域添加到[RFC6303]中建立的“IPv4本地服务DNS区域注册表”。

Unlike the addresses described in [RFC1918], which are not expected to be seen by other parties, the addresses defined by [RFC6598] are expected to be seen by parties other than those deploying the addresses. Therefore, it is more crucial that recursive nameservers default to serving these zones locally.

与[RFC1918]中描述的其他方不希望看到的地址不同,[RFC6598]中定义的地址预期会被部署地址的其他方看到。因此,更重要的是递归名称服务器默认在本地为这些区域提供服务。

2. Changes to the IPv4 Locally-Served DNS Zones Registry

IANA has added the zones listed in "RFC 6598 Zones" (Section 2.1) to the "IPv4 Locally-Served DNS Zone Registry".

3. IANA Considerations
3. IANA考虑

Per this document, IANA has added the zones listed in "RFC 6598 Zones" (Section 2.1) to the "IPv4 Locally-Served DNS Zone Registry".

根据本文件,IANA已将“RFC 6598区域”(第2.1节)中列出的区域添加到“IPv4本地服务DNS区域注册表”中。

IANA is reminded that an insecure delegation for these zones is required for compliance with [RFC6303] to break the DNSSEC chain of trust.

提醒IANA,为了遵守[RFC6303],打破DNSSEC信任链,需要对这些区域进行不安全的授权。

4. Security Considerations
4. 安全考虑

This document does not present additional security risks to the Internet than those described in [RFC6303] and [RFC6598].

与[RFC6303]和[RFC6598]中所述的安全风险相比,本文件不会对互联网带来额外的安全风险。
