• determining whether the particular FQDN included with the DNS query request is included in the FQDNs or IP addresses associated with the plurality of DNS configuration policies;
• responsive to determining that the particular FQDN is not included in the FQDNs or IP addresses associated with the plurality of DNS configuration policies, directing the DNS query request to an alternative DNS destination;
• 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
