Description
Indicates whether the phone has DHCP enabled
or disabled.
When DHCPv6 is enabled, the DHCPv6 server
assigns the phone an IPv6 address. When DHCP
v6 is disabled, the administrator must manually
assign an IPv6 address to the phone.
The DHCPv6 setting along with the Auto IP
Configuration setting determine how the IP
phone obtains its network settings. For more
information on how these two settings affect
the network settings on the phone, see
and Autoconfiguration, on page
Internet Protocol version 6 (IPv6) address of

must also assign the IPv6 prefix length and
default router. See IPv6 Prefix Length in this
table.

The subnet prefix length is a decimal value from
1 to 128, that specifies the portion of the IPv6
address that comprises the subnet.

The phone obtains information on the
Note
default router from IPv6 Router
Advertisements.
Primary Domain Name System (DNS) server
(DNS Server 1) and optional backup DNS
servers (DNS Server 2) used by the phone.

server in the following order:
1 IPv6 DNS Server 1
2 IPv6 DNS Server 2
3 DNS Server 1-5 for IPv4 (respectively)
