DNS Root Name Service Protocol and Deployment Requirements
draft-blanchet-iab-2870bis-00.txt

Abstract

The DNS Root Name service are a critical part of the Internet architecture. The protocol and deployment requirements expected to be implemented for the DNS root name services are defined in this document. Operational requirements are out of scope. This document obsoletes and reclassifies RFC2870 as Historic.

Table of Contents

1. Introduction

[RFC2870] discusses protocol and operational requirements for root name servers for Internet's domain name system(DNS) protocol [RFC1035]. Since its publication, both protocol and operational requirements have evolved. The concensus of the community is to separate the two sets of requirements into two documents. The operational requirements are defined in [RSSAC-001]. This document defines the protocol requirements and some deployment requirements.

The root servers are authoritative servers of the unique [RFC2826] root zone (".")[ROOTZONE], the root-servers.net zone, and the zone for the .arpa top-level domain[ARPAZONE]. This document describes the external interface of the root name servers from a protocol viewpoint of the service. It specifies basic requirements for the Internet that DNS clients meet when interacting with a root name service over the public Internet.

The keywords MUST, MUST NOT, REQUIRED, SHALL, SHALL NOT, SHOULD, SHOULD NOT, RECOMMENDED, MAY, and OPTIONAL, when they appear in this document, are to be interpreted as described in BCP 14, [RFC2119].

1.1. RFC 2870 as Historic

This document obsoletes and reclassifies [RFC2870] as Historic.

2. Protocol Requirements

This section describes the high-level protocol requirements. Operative details are not discussed and are left to the operators of the root name service.

The root name service:

3. Deployment Requirements

The root name service:

4. Security Considerations

This document does not specify a new protocol. However, the root name servers are a key component of the Internet architecture and play a key role into the overall security of the Internet[RFC2826]. Specific security considerations on the DNS protocols are discussed in their respective specifications. The security considerations on the operational side of the root name servers are discussed in [RSSAC-001].

5. IANA Considerations

This document has no action for IANA.
