DHCPv6 Extension Practices and Considerations
draft-ietf-dhc-problem-statement-of-mredhcpv6-06
Abstract
IP addresses as the communication identifier bear more and more
properties to meet different requirements. The privacy protection,
accountability, security, and manageability of networks can be
supported by extending the DHCPv6 protocol according to requirements.
This document provides current extension practices and typical DHCPv6
server softwares on extensions, defines a DHCPv6 general model,
discusses some extension points, and presents extension cases.

1. Introduction
The IP address plays a significant role in the communication on the
Internet. IP address generation is also closely related to the
privacy protection, accountability, security, and manageability of
networks. Dynamic Host Configuration Protocol for IPv6 (DHCPv6)
[RFC8415] is a critical network protocol that can be used to
dynamically provide IPv6 addresses and other network configuration
parameters to IPv6 nodes. DHCPv6 continues to be extended and
improved through new options, protocols, and message processing
mechanisms.
Although DHCPv6 provides more and more comprehensive functionalities
and DHCPv6 server softwares also provide extension interfaces to
allow administrators to alter and customize the way how they handle
and respond to DHCPv6 messages, there is still a lack of
comprehensive insight into where and how to conduct extensions in
