Type (1 byte): This field MUST be set to 0x08.
Length (1 byte): This field MUST be set to 0x10.
IPv6 Address (16 bytes): This field specifies an IPv6 address of the responder. This field's value MUST be an address of the network interface over which the frame is sent, if it has an IPv6 address. If there are multiple IPv6 addresses on the network interface, the device is free to choose any one of them. If an IPv6 address is not available on the network interface over which the frame is sent, the device MAY use an IPv6 address on a different network interface. However, if the responder sets the MW bit in the Characteristics attribute, the address MUST be one which is reachable via the interface over which the frame is sent, and if there is no such address, the responder MUST NOT include the IPv6 Address attribute.
