Abstract
A method may include obtaining Domain Name System (DNS) configuration policies, that indicate how to direct a DNS query based on various Internet Protocol (IP) addresses or Fully Qualified Domain Names (FQDNs). The method may include obtaining a DNS query request on a first interface adapter in which the DNS query request is obtained from a DNS client and directed toward a particular FQDN. The method may include determining whether the particular FQDN included with the DNS query request is included in the DNS configuration policies and directing the DNS query request to an alternative DNS destination responsive to determining that the particular FQDN is not included in the DNS configuration policies. The method may include generating, at the alternative DNS destination, a DNS response that includes an error code, injecting the DNS response into a Transport Control Protocol (TCP)/IP stack, and sending the DNS response to the DNS client.
