Unspecified Address

Unspecified Address
An unspecified IPv6 address is a special address that is used as a placeholder by a device that does
not have an IPv6 address. This might happen when the node requests an address from a DHCP
server or when the duplicate address detection packet is sent. The format is 0:0:0:0:0:0:0:0 but can
be represented by 0::0 or just ::/128. This IPv6 address cannot be assigned to any interface and
should not be used as a destination address.
