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 Reverse resolution: The process by which a recursive DNS resolver can look up the names of a given IP address by following a chain of referrals from the root zone to either the in-addr.arpa zone or the ip6.arpa zone.
1.3 Early registration: IPv4 address space assigned or allocated before the establishment of the Regional Internet Registries (RIRs).

1.0 Introduction

The RIPE NCC provides, as part of its services, 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 Introduction

The RIPE NCC provides the necessary support to enable 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].
2.0 Obtaining Delegation of an in-addr.arpa or ip6.arpa sub-domain

The RIPE NCC provides reverse delegation for address space that has been allocated or assigned by the RIPE NCC. It also provides systems to control reverse delegations relating to early registrations that have been transferred to the RIPE Database. Registrants of address space allocations or assignments 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.
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.
