Consider the case of a Router-on-a-Stick topology with multiple vlan tags, when a new computer joins the network.
Will the DAD Neighbor Solicitation message be tagged with a VLAN? Will all the computers in the network receive one even with the different VLAN Tag?
Another scenario, let say there are no Router-on-a-Stick or inter-vlan, when a computer asks for an address will everyone still receive an Neighbor Solicitation, or just the computers in the same VLAN?
