I have setup an MS Windows 2016 server Hyper-V Host with 3 Hyper-V Servers. The NIC has 4-ports. All seems to work fine.
However, I'm not sure I configured correctly. The attached pdf shows the Network Sharing Adaptor screen of the Host and one of the Hyper-V servers. On the Host, there are 7 connections on the Network and Internet view. The Host is fine with its static IP but the Hyper-V servers created the Hyper-V Virtual Ethernet Adaptor as well has the HP Ethernet Port it is assigned. The Hyper-V Virtual Ethernet adaptors assigned a DHCP IP address. In looking at one of the Hyper-V servers (bottom first page of pdf), it only has the Adaptor I created and selected in the Hyper-V settings which I configured with a static IP.
My uncertainty at issue is that on the Host, the Hyper-V Virtual Ethernet Adaptors with the DHCP addresses shows up in DNS as Ball18 - 4 times. Have I made a mistake in this configuration or is it doing what it is supposed to do? I would think that DNS having 4 entries as Ball18 with 4 different IPs would be inaccurate. The 2nd page shows the sample server hyper-V settings in which I created the Adaptors #2, #3, and #4 for each HV server.
