Vendor ID Enter the Vendor Class Identifier, such as the type of the hardware or firmware.
option 61 Select this and enter any string that identifies the device.
IAID Enter the Identity Association Identifier (IAID) of the device, for example, the WAN connection
index number.
DUID Enter the hardware type, a time value and the MAC address of the device.
option 125 Select this to have the Zyxel Device automatically generate and add vendor specific
parameters in the DHCP discovery packets that go to the DHCP server.
IPv6 Address (This is available only when you select IPv4 IPv6 DualStack or IPv6 Only in the IPv4/IPv6 Mode field.)
Obtain an IPv6
Address

Static IPv6
Address
Select Static IPv6 Address if you have a fixed IPv6 address assigned by your ISP. When you select
this, the following fields appear.
IPv6 Address Enter an IPv6 IP address that your ISP gave to you for this WAN interface.
Prefix Length Enter the address prefix length to specify how many most significant bits in an IPv6 address
compose the network address.
IPv6 Default
