Abstract
An encrypted message comprising a DNS request may be received from a client device. The DNS request may be decrypted to determine an IP address and a port associated with the client device. A security token may be determined based on the IP address and the port. A message comprising an indication of the DNS request and the security token may be sent to a DNS server. A reply comprising a payload and the security token may be received from the DNS server. Based on the security token, an indication of the payload of the reply may be sent to the client device.
