A separate mailing list is used for discussing the IPv6 version of dhcp: dhcp-v6@bucknell.edu.
This working group has developed DHCP for automated allocation, configuration and management of IP addresses and TCP/IP protocol stack parameters. DHCP is currently a "Draft Standard" (RFC2131, RFC2132). The working group now has four main objectives:
* Revise and submit the DHCP specification for acceptance as a Full Standard
* Develop a roadmap for the review and acceptance of new options, define a new option syntax, develop an accurate list of assigned option codes and identify option codes that can be safely reassigned
* Develop a specification for DHCP for IPv6
* Develop an inter-server communication for coordination of multiple servers
* Review new options for DHCP, as deemed appropriate by the working group chair and/or the Internet area directors; specific options currently under review in the working group include:
o Mechanisms for the authentication of clients and servers
o Interaction between DHCP and DNS dynamic update protocol
o Definition of a DHCP MIB for management of DHCP servers through SNMP
o Definition of an LDAP schema to provide a standardized format for the storage and retrieval of DHCP information, primarily configuration and lease data; this schema will be developed in coordination with the Policy Frameworks Working Group as appropriate.
o Options through which DHCP relay agents can pass information to DHCP servers
o Other options: user class, server selection, domain search

Summary of DHC WG meetings in Minneapolis.
Monday, 1530-1730 - DHCPv4 agenda items
DHC WG activities update Ralph Droms, 10 minutes
Droms announced that the relay information option, load balancing and authentication specs have been accepted as draft standards.
DHCP Option for SIP Servers Henning Schulzrinne, 20 minutes
http://www.cs.columbia.edu/~hgs/sip/drafts/draft-ietf-sip-dhcp-04.txt
The WG finds this option acceptable in principle; however, the specific format and encoding of data in the option is still an issue. Authors want simple ASCII text encoding of DNS name or dotted decimal IP address; WG recommends RFC1035 encoding for DNS name and binary encoding of IP address with flag to indicate which encoding is in use. WG has selected RFC1035 for other recent options.
Addition of Device Class to Agent Options Rich Woundy, 10 minutes
draft-ietf-dhc-agentoptions-device-class-01.txt
This spec is ready for WG last call.
The DHCP Client FQDN Option Mark Stapp, 10 minutes
draft-ietf-dhc-fqdn-option-01.txt
Resolution of DNS Name Conflicts Among DHCP Clients
draft-ietf-dhc-ddns-resolution-01.txt
Author will rev spec, changing "MUST implement" to "SHOULD implement"; spec will then we ready for WG last call and fixing words for IPv6.
Encoding Long DHCP Options Ted Lemon, 10 minutes
draft-ietf-dhc-concat-00.txt
This draft enables the CSR option and domain name search list (as well as other future options) that may require more than 255 data bytes. Kim Kinnear will forward spec fixes to author. Next rev of spec will be ready for WG last call.
The Classless Static Route Option for DHCP Ted Lemon, 10 minutes
draft-ietf-dhc-csr-04.txt
This draft depends on the long DHCP options draft. Bernie Volz will forward spec fixes to author. Next rev of spec will be ready for WG last call.
DHCP Failover Protocol Kim Kinnear, 5 minutes
draft-ietf-dhc-failover-08.txt
Kinnear will review last call comments and issue concerning addresses in protocol (does NAT affect server-server identification using IP addresses?). Next rev of spec will be ready for WG last call.
DHCP Lease Query Kim Kinnear, 10 minutes
draft-ietf-dhc-leasequery-01.txt
Spec requires further work with input from WG:
1. Put multiple returns from client query into
dhcp-requested-address options.
2. Allow configuration of server for which IP address it returns
as the "most current" one (i.e., in the return packet instead
of in the DHCP requested address options).
3. Resolve the client-requested-host-name option along with
the FQDN option.
4. Go forward with the client-last-transaction time.
Subnet Selection sub-option for Relay Agent Information Option Kim Kinnear, 15 minutes
draft-kinnear-agent-subnet-selection-00.txt
This spec is ready for WG last call.
DHCP VPN Information option
draft-johnson-vpn-id-option-00.txt
VPN Identifier sub-option for Relay Agent Information Option
draft-kinnear-agent-vpn-id-00.txt
These specs will be taken on as DHC WG work items.
Triggering AAA from DHCP Relay Agents George Tsirtsis, 20 minutes
draft-ietf-dhc-aaa-ra-00.txt
Author will work with Droms and Schnizlein to revise draft.
Extensions to DHCP for Roaming Users Biswaroop Mukherjee, 15 minutes
draft-mukherjee-dhc-dhcproam-01.txt
This spec will be taken on as a DHC WG work item.
-------------------------------------------------------------------------------
Wednesday, 0900-1130 - DHCPv6 review
Report from DDDT (Dynamic DNS Design Team) Rich Draves, 15 minutes
The DDDT has developed an "Analysis of DNS Server Discovery Mechanisms for IPv6" <draft-ietf-ipngwg-dns-discovery-00.txt>. One of the discovery mechanisms uses DHCP messages and semantics to pass DNS server information to clients. Aboba presented a summary of the report for the information of the DHC WG.
Dynamic Host Configuration Protocol for IPv6 (DHCPv6) Jim Bound, Ralph Droms
draft-ietf-dhc-dhcpv6-17.txt
- Review of changes in current draft
- Review of design team teleconference
Summary of changes:
* Added new messages: Confirm, Renew, Rebind, Decline
* Uniform format for all client-server messages
* Clarified relay agent forwarding
* Advertise messages include offered addresses for client selection
* Clients multicast all messages to accommodate relay agent options; will add new option to allow server control of use of unicast
* New Reconfigure-init semantics - "trigger" reconfigure state
Changes accepted by WG except for:
* Reconfigure-init - punt on multicast reconfigure-init
* Spec needs review of options - which are required in base spec?
* Spec needs review of error codes
Authors will revise spec according to WG input from meeting discussion and based on input from Francis Dupont.
- Discussion of outstanding issues
* Temporary addresses
* IA identification
* DHCP-DNS interaction
WG will continue to consider these issues through the WG mailing list.
