Understanding DHCPv6 and Autoconfiguration

You can choose to configure the IP address and other network settings, such as the TFTP server, DNS
server, domain, name, etc. on an IP phone manually or by using a router and/or a DHCP server to
automatically assign the IP address and other network information. For more information on how the
Auto IP Configuration and DHCPv6 settings determine where the IP Phone acquires its IPv6 address and
other network settings, see

How the Phone Acquires its IP address and Network Settings
You must manually configure an IP address and the other network settings.
Note
You must manually configure an IP address and the other network settings.
Note
The DHCP server assigns the IP address and the other network settings to the
phone.
When the M-bit is set on the router, the O-bit is ignored. The phone can set
its IPv6 address based on an IPv6 address that it received from a DHCPv6
server or the phone can acquire its IPv6 address through stateless address
autoconfiguration.
When the M-bit is not set, you should set the O-bit on the router. The phone
will then acquire its IPv6 address through stateless address
autoconfiguration. It will not request an IPv6 address from the DHCPv6
server, but it will request other network configuration information.
