Hi Team,

During an investigation i noticed that when using custom Service CIDR like 192.168.0.0/16 where the kube-dns service ip is 192.168.0.10 karpenter's nodepool is still defaulting the kube-dns service ip to 10.0.0.10, therefore when new pods are scheduled, it gets the IP 10.0.0.10 in the /etc/resolv.conf.

After discussing this with our PG:
it seems like Node autoprovisioning doesn't support custom Service CIDR while in preview, it would be best to change our documentation. According to the PG this will be supported in GA.
