3/2/2004dhc WG - IETF 59, Seoul5 Vendor-Specific Suboption for the DHCP RAIO draft-stapp-dhc-vendor-suboption-00 Provides same function as vendor-specific options in client-server messages Encoded like vendor-identifying options

3/2/2004dhc WG - IETF 59, Seoul6 Dual-stack issues Pose issues briefly –How do dual-stack hosts configure IPv4 and IPv6 parameters? –Client: One or two clients Merging configuration from multiple sources –Server: One or two servers Management coordination and complexity Internet Draft describes issues WG will consider issues and alternatives and come to consensus on solution

3/2/2004dhc WG - IETF 59, Seoul7 Charter WG needs to review charter for progress, consider update to charter for new work (renumbering for stateless DHCPv6, dual stack issues)?, update milestones Will look at major pieces of charter independently

3/2/2004dhc WG - IETF 59, Seoul8 Charter – part 1 The dhc working group (DHC WG) has developed DHCP for automated allocation, configuration and management of IP addresses and TCP/IP protocol stack parameters. DHCP is currently a "Draft Standard". The base protocol is documented in RFC2131 and RFC2132 (DHCP for IPv4) and RFCxxxx (DHCP for IPv6). Additional options are documented in subsequent RFCs.

3/2/2004dhc WG - IETF 59, Seoul9 Charter – part 2 The DHC WG is responsible for reviewing (and sometimes developing) DHCP options or other extensions (for both IPv4 and IPv6). The DHC WG is expected to review all proposed extensions to DHCP to ensure that they are consistent with the DHCP specification and other option formats, that they do not duplicate existing mechanisms, etc. The DHC WG will not (generally) be responsible for evaluating the semantic content of proposed options. The DHC WG will not adopt new proposals for extensions to DHCP as working group documents without first coordinating with other relevant working groups and determining who has the responsibility for reviewing the semantic content of an option.

3/2/2004dhc WG - IETF 59, Seoul10 Charter – DHCP Security The DHC WG will address security in DHCP Develop and document security requirements for DHCP. RFC 3118 defines current security mechanisms for DHCPv4. Unfortunately, RFC 3118 has neither been implemented nor deployed to date. Specific issues to be considered include: –Improved key management and scalability –Security for messages passed between relay agents and servers –Threats of DoS attacks through FORCERENEW –The increased usage of DHC on unsecured (e.g., wireless) and public LANs –The need for clients to be able to authenticate servers, without simultaneously requiring client authentication by the server. Develop and document a roadmap of any new documents or protocols needed to meet the security requirements for DHCP

3/2/2004dhc WG - IETF 59, Seoul11 Review RFC 2131, RFC 2132 Write an analysis of the DHCP specification, including RFC2131, RFC2132 and other RFCs defining additional options, which identifies ambiguities, contradictory specifications and other obstacles to development of interoperable implementations. Recommend a process for resolving identified problems and incorporating the resolutions into the DHCP specification.
