Server 2012 Teamed NIC Configuration with HyperV

Hi,

We have just rolled to server 2012 for our HyperV hosts. I have configured three NIC Teams as follows:

Now my question is :

Should the Multiplexer adapters have an IP address ? they do receive address via DHCP. Is that normal?

There are now 3 Different NIC Adapters, 1- Physical Nic Adapter, 2- Microsoft Network Adapter Multiplexer Driver, 3- vEthernet (Microsoft Network Adapter Multiplexor Driver Virtual Switch) --> what are these network cards do in relation to HyperV.

Pardon my lack of knowledge in this respect.

Thanks
