What version of Go are you using (go version)?

$ go version
go version go1.16.5 darwin/amd64

Does this issue reproduce with the latest release?

What did you do?

Tried to query root zone NS records, to emulate

dig -t ns -q .

func main() {
	r, err := net.LookupNS(".")

	if err != nil {
		fmt.Printf("%v\n", err)
		return
	}
	fmt.Println(len(r), r)
}

What did you expect to see?

List of ns records.

What did you see instead?

lookup .: no such host
