Abstract

This document describes the policy for reverse delegation of IPv4 and IPv6 address space in the RIPE NCC service region.

1.0 Definition

1.1 Reverse delegation: The process by which the authority for certain reverse DNS zones is assigned to a specific set of DNS servers.

1.2 Early registration: IPv4 address space assigned or allocated before the establishment of the Regional Internet Registries (RIRs).

2.0 Introduction

The RIPE NCC provides, as part of its services, provides the necessary support to enable the reverse resolution of IPv4 and IPv6 address space into domain names. This service is implemented under the in-addr.arpa and ip6.arpa sub-domains described in [1] and [2].

Reverse delegations for IPv4 and IPv6 addresses allocated by the RIPE NCC are made to Local Internet Registries (LIRs) and further delegated by the LIRs to Internet Service Providers or End Users.

2.0 Obtaining Delegation of an in-addr.arpa or ip6.arpa sub-domain

3.0 Reverse Delegation in the RIPE NCC Service Region

The RIPE NCC provides reverse delegation for address space that has been allocated or assigned delegations for IPv4 and IPv6 address space that is registered by the RIPE NCC. It The RIPE NCC also provides systems to control reverse delegations relating to delegation of early registrations that have been transferred to the RIPE Database. Registrants of address space allocations or assignments Address space holders may delegate authority

for requesting reverse delegation from the RIPE NCC.

The RIPE NCC accepts requests for reverse delegation for address space that has been allocated by the RIPE NCC to an LIR or, in the case of PI address space, an assignment that has been made to an End User.
