626 Configuring IPv6
DHCPv6
DHCP is generally used between clients (for example hosts) and servers (for example routers) for the
purpose of assigning IP addresses, gateways, and other networking definitions such as DNS, NTP, and/or
Session Initiation Protocol (SIP) parameters. However, IPv6 natively provides for auto configuration of IP
addresses through IPv6 Neighbor Discovery Protocol (NDP) and the use of Router Advertisement
messages. Thus, the role of DHCPv6 within the network is different than that of DHCPv4 in that it is
less relied upon for IP address assignment.
There is a list of DHCP options that is comm only supported by DHCPv4 that need t o be supported also
by DHCPv6, and must be configured.
NOTE: The most important DHCP option to configure is the DNS Server option, whi ch is configured on the IPv6
