Hello All,
I have a 3 node 2016 Hyper-V Failover Cluster running 20 VMs. When looking at the Networking tab at the bottom of VMM (not the individual VM network adapter settings), five of the VMs display IPv6 addresses starting with fe80::. Four of the VMs are using Dynamic adapters, one is using static. All VMs are also Windows Server 2016. Four of the VMs are on the same node, one VM on a second node. There are a total of 4 Virtual Networks, but DNS, AD, etc, exists only on the "Management" Virtual Network.
I assume these are link local addresses and not in use. I don't understand why all the VMs do not exhibit this same behavior.
There are no IPv6 addresses in DNS, I just looked. For every NIC in every VM, I unchecked the box labeled "Register this connection's address in DNS" box in the Advanced DNS properties page of the Internet Protocol Version 6 (TCPIP/IPv6) protocol.
I am wondering how this happened and how to get rid of the IPv6 addresses in VMM.
Thanks,
Vint
Thanks, Vint
