Abstract DNSSEC Lookaside Validation (DLV) is a mechanism for publishing DNSSEC trust anchors outside of the DNS delegation chain. This document asks IANA to create a DLV registry containing entries for TLDs as well as the reverse-tree delegations maintained by IANA.

Introduction This document assumes familiarity with DNSSEC Lookaside Validation (DLV) [I-D.weiler-dnssec-dlv] as well as the core DNSSEC specifications [RFC4033] [RFC4034] [RFC4035]. The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in RFC 2119 [RFC2119]. 2. IANA Considerations IANA is asked to create a DLV registry at dlv.dnssec.arpa targeting the root and containing DLV records for those TLDs and reverse zones delegated directly by IANA that ask to have DLV records published for their own zones. IANA is instructed to use its own best practices for authenticating zone operators' requests to insert, modify, and delete DLV entries. This DLV registry MUST itself be signed with DNSSEC. To be clear, IANA is only being asked to publish DLV records for top level domains and reverse zones delegated directly from IANA, thereby taking advantage of the IANA's existing relationships with the these zone operations and established procedures for authenticating requests from these zone operators. 3. Security Considerations General security considerations for DLV are discussed in [I-D.weiler-dnssec-dlv]. A DLV registry is a signed zone, much like any other. IANA is asked to use ordinary operating procedures for this signed zone, as described in [RFC4641]. In particular, it is suggested that IANA use 2048-bit RSA keys for both the KSK and ZSKs in this zone and roll the KSK at least once per year for the first four years this registry is in operation. (The ZSK will presumably be rolled somewhat more often.) IANA is encouraged to generate several KSKs for this zone immediately and publish a hash of each of those keys, perhaps in the form of a DS record, at the time the registry goes into production service. 4.
