Abstract: Embodiments are directed to automatically redirecting DNS requests for DNS names while the DNS names are not resolvable. In one scenario, a domain name system (DNS) server establishes a wildcard DNS entry for a specified domain name. Incoming DNS requests for that domain name are automatically forwarded to a load balancer. The load balancer inspects packet headers for each received DNS request to determine which hostname was indicated in the DNS request. The load balancer then accesses a mapping file to determine which back-end server the DNS request is to be redirected to based on the hostname indicated in the packet header and, based on the determination, forwards the received request to the determined back-end server.
