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 the necessary support to enable 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 Link: #ref1 ] and [2] Link: #ref2 .

3.0 Reverse Delegation in the RIPE NCC Service Region

The RIPE NCC provides reverse delegations for IPv4 and IPv6 address space that is registered by the RIPE NCC.

The RIPE NCC also provides systems to control reverse delegation of early registrations that have been transferred to the RIPE Database.

Address space holders may delegate authority to another party.

4.0 Procedures
