Failover Clustermanager Cluster Network – Network Interface only shows IPv6 Localloop

The todays post is inspired by some questions I often see when look around in forum for microsoft clustering.

Many people who are using Microsoft Failover Cluster Manager the first time, encounter that they see an unnamed cluster network with an IPv6 Loopback adresse.



Often they see it as a failure in Cluster manager. That is not the case. Mostly the reason is very simple. You have a Networkcard in your system which has no IPv4 or any IP at all.


Now you need to find why the reason why you don’t got an IP. The most common reasons are:

– you have no DHCP Server in that network and no static IP configured
– you get no IP from the DHCP server because of wrong VLAN or Port is not cabled correctly

So the easiest and most common issue is, that you forgot to set the IP. So set the IP for that networkcard.


After you set the IP your Failover Cluster Manager sees the new IP and everything looks fine 🙂
