Dns is part of stock k8s. It usually runs on the 10th ip of the services network. It's the first service that goes up after you've initialized the cluster and initially serves only internal requests. Nothing stops you from pointing the matching lookup zone to the internal dns of k8s, however. I've done it before and it worked great for lan requests. If you want to expose it to the internet however, an automatically configured dns is probably not what you want, unless you actually have a public ip range to use with said services. In that case, the original comment makes more sense and you'd just add a wildcard dns to your ingress controller, which can be traefic or whatever else you want
