What if the Domain Name System (DNS) ensured that only authenticated and authorized users could access a company’s email server or VPN gateway?

So-called Authenticated Resolution would require that the client machine authenticate to the DNS name server; it would return a network address response only if the client is authorized to access the resources it’s requesting via the domain request. Authenticated Resolution also could also help thwart distributed denial-of-service (DDoS) attacks — attackers wouldn’t be able to access the actual addresses of their targets because they would not be authorized to do so.
