Droms Expires January 6, 2011 [Page 1] Internet-Draft DHCPv6 IANA Rules July 2010 1. Introduction This document modifies the IANA rules for some DHCPv6 (Dynamic Host Configuration Protocol for IPv6) [RFC3315] registries. Rules for the following protocol registries are affected: o DHCP Message Types [RFC3315] o DHCP Option Codes [RFC3315] o Status Codes [RFC3315] o DUIDs [RFC3315] o OPTION_LQ_QUERY Option [RFC5007] o IEEE 802.21 Service Type [RFC5678] The rules for these registries are modified because there can be situations in which it is reasonable to grant an allocation in one of these registries under special circumstances. Other DHCPv6 registries already use "Standards Action or IESG Approval" as the Registration Procedures. In addition to changing the Registration Procedures for the DHCP Message Types registry, four new DHCP Message Types are added for use in experimentation and testing. The IESG, when this document was written in June, 2010, was reviewing a document for publication that required a new registration in the DHCP Option Codes registry. The document defined a new DHCPv6 option defined by the SIP Forum, but was an independent submission to the IESG and intended for Informational Status. Thus, the document would not meet the Option Code Registration Procedures of "Expert Review and Standards Action". By changing the Option Codes Registration Procedures to "Standards Action or IESG Approval", the IESG can approve such registrations after review and consideration of the special circumstances. 2. IANA Considerations IANA is requested to update the Registration Procedures for the DHCPv6 registries DHCP Message Types, DHCP Option Codes, Status Codes, DUIDs, OPTION_LQ_QUERY option and IEEE 802.21 Service Type as specified below. In addition, IANA is requested to add four new DHCP Message Types, which are to be used for experimentation and testing. All other DHCPv6 IANA Registrations Procedures are to remain Droms Expires January 6, 2011 [Page 2] Internet-Draft DHCPv6 IANA Rules July 2010 unchanged. 2.1. DHCP Message Types The Registration Procedures for the DHCP Message Types registry are "Standards Action or IESG Approval." Previously, the Registration Procedures were "Expert Review and Standards Action." The following four DHCP Message Type values are reserved for experimentation and testing: Value Description Reference ----- ----------- --------- 65532 (0xfffc) EXPERIMENTAL [thisRFC] 65533 (0xfffd) EXPERIMENTAL [thisRFC] 65534 (0xfffe) EXPERIMENTAL [thisRFC] 65535 (0xffff) EXPERIMENTAL [thisRFC] As these message types reserved for experimental and testing purposes, no guarantee is made for interoperability among DHCPv6 clients, servers and relay agents that use these experimental message types. 2.2. DHCP Option Codes The Registration Procedures for the DHCP Option Code registry are "Standards Action or IESG Approval." Previously, the Registration Procedures were "Expert Review and Standards Action." 2.3. Status Codes The Registration Procedures for the Status Codes registry are "Standards Action or IESG Approval." Previously, the Registration Procedures were "Standards Action." 2.4. DUIDs The Registration Procedures for the DUIDs registry are "Standards Action or IESG Approval." Previously, the Registration Procedures were "Standards Action." 2.5. OPTION_LQ_QUERY option The Registration Procedures for the OPTION_LQ_QUERY option registry are "Standards Action or IESG Approval." Previously, the Registration Procedures were "Standards Action." Droms Expires January 6, 2011 [Page 3] Internet-Draft DHCPv6 IANA Rules July 2010 2.6. IEEE 802.21 Service Type The Registration Procedures for the IEEE 802.21 Service Type registry are "Standards Action or IESG Approval." Previously, the Registration Procedures were "Standards Action." 3. Security Considerations This specification does not change the security properties of DHCPv6 and the specific components of DHCPv6 documented in the affected registries. 4.

Changes from RFC 3315, RFC 5007 and RFC 5678 This document changes the IANA Registration Procedures for the DHCPv6 DHCP Message Types, DHCP Option Codes, Status Codes, DUIDs, OPTION_LQ_QUERY option and IEEE 802.21 Service Type registries. Ir also adds four DHCP Message Type values, which are reserved for experimentation and testing.
