I am trying to force my ubuntu 22.04 systems to use google's internal dns resolvers for all queries, but seem to have a disconnect somewhere. I have changed /etc/resolv.conf to:
nameserver 169.254.169.254search google.internalInside of google cloud I have setup an internal dns zone for internal.gce which works when I use dig on the same host:
