In our case, we have a lot of IPv6 only kubernetes clusters, which are
named `xx.k8s.ooo` and have a world wide rachable CoreDNS server built
in. In this case, we want to allow the domain c1.k8s.ooo to be world
reachable, so we configure the dual stack server

### Step 4: adjusting the zone file
In case you are running an IPv6 only server, you need to configure the
upstream DNS server. In our case this looks as follows:
```
; The domain: c1.k8s.ooo
c1 NS kube-dns.kube-system.svc.c1
; The IPv6 only DNS server
kube-dns.kube-system.svc.c1 AAAA 2a0a:e5c0:2:f::a
; The forwarding IPv4 server
kube-dns.kube-system.svc.c1 A 194.5.220.43
