Internet Engineering Task Force B. Volz INTERNET DRAFT Ericsson Expires: August 2003 April 4, 2003 Site Specific Options for DHCP for IPv6 draft-volz-dhc-dhcpv6-site-options-00.txt Status of this Memo This document is an Internet-Draft and is in full conformance with all provisions of Section 10 of RFC2026. Internet-Drafts are working documents of the Internet Engineering Task Force (IETF), its areas, and its working groups.

Internet-Drafts are draft documents valid for a maximum of six months and may be updated, replaced, or obsoleted by other documents at any time.

Abstract This document specifies that a portion of the DHCP for IPv6 [DHCPv6] 16-bit option space is reserved for site-specific options. Site- specific options are to be used for site specific needs and MUST NOT be used for public (IANA assigned) or vendor specific options. 1. Introduction The DHCP for IPv6 base specification [DHCPv6] did not reserve a range of option numbers for private use within sites, as was defined for DHCP for IPv4 [RFC2132]. This document specifies that a portion of the DHCP for IPv6 16-bit option space is reserved for site-specific options. Site-specific options are to be used for site specific needs and MUST NOT be used for public (IANA assigned) or vendor specific options.

Requirements The keywords MUST, MUST NOT, REQUIRED, SHALL, SHALL NOT, SHOULD, SHOULD NOT, RECOMMENDED, MAY, and OPTIONAL, when they appear in this document, are to be interpreted as described in RFC 2119 [RFC2119]. 3. Site-Specific Options The DHCP for IPv6 option codes from 65,280 to 65,534 are to be reserved for use by site-specific options. This reserves 254 option values for site-specific use. This range of option codes MUST NOT be assigned by IANA to any public options. This document does not define the behavior of clients, servers, and relay agents with respect to site-specific options, as these are site issues. However, it is recommended that client implementations: a. allow the list of site-specific options to be included in an Option Request Option (DHCPv6) to be configured, b. allow the list of site-specific options and the corresponding values to be sent in client request messages to be configured, and c. allow application software to obtain the data returned for site- specific options. 4. IANA Recommendations IANA is requested to reserve the DHCP for IPv6 options from 65,280 to 65,534 (decimal), inclusive, for site-specific options. IANA will not manage these options; sites will manage this space. 5. Security Considerations This document in and by itself provides no security, nor does it impact existing security.
