F. Gont: AUTHOR [+3]
This document specifies DHCPv6-Shield, a mechanism for protecting hosts connected to a switched network against rogue DHCPv6 servers [RFC3315]. The basic concept behind DHCPv6-Shield is that a layer 2 device filters DHCPv6 messages intended for DHCPv6 clients (henceforth, "DHCPv6-server messages"), according to a number of different criteria. The most basic filtering criterion is that DHCPv6-server messages are discarded by the layer 2 device unless they are received on specific ports of the layer 2 device.

DHCPv6-Shield: Protecting against Rogue DHCPv6 Servers
This document specifies a mechanism for protecting hosts connected to a switched network against rogue DHCPv6 servers. It is based on DHCPv6 packet filtering at the layer 2 device at which the packets are received. A similar mechanism has been widely deployed in IPv4 networks ('DHCP snooping'); hence, it is desirable that similar functionality be provided for IPv6 networks. This document specifies a Best Current Practice for the implementation of DHCPv6-Shield.
