Option Description To Change
DHCPv6 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 Table 4-5.
1. Unlock network configuration options.
2. Scroll to the DHCPv6 option and press the No
softkey to disable DHCP, or press the Ye s
softkey to enable DHCP.

IPv6 Address Internet Protocol version 6 (IPv6) address of the
phone. The IPv6 address is a 128 bit address.
If you assign an IP address with this option, you
must also assign the IPv6 prefix length and default
router. See the IPv6 Subnet Prefix option in this
table.
