Communication using DNS repurposing

A method for communicating using embedded DNS messages, the method comprising:

• selecting a query domain corresponding to a destination DNS server,
• wherein the destination DNS server is authoritative for servicing DNS requests for the selected query domain;
• generating a message configured to be:
• parsed from a DNS lookup request by a destination DNS server as data distinct from a DNS domain of the DNS lookup request, and
• combined with the query domain to fit within a question portion of the DNS lookup request,
• wherein the message comprises an identification of a parsing algorithm to use to extract data from the DNS lookup request;
• generating the DNS lookup request, the DNS lookup request comprising a question portion that includes a combination of the generated message and the query domain,
• so that the question portion of the DNS lookup request includes both the generated message and the query domain,
• wherein the query domain of the DNS lookup request is used to route the DNS lookup request to a DNS server providing a mapping between the query domain and an IP address;
• and
• transmitting the DNS lookup request.

A computer-readable memory storing instructions configured to, when executed by a computing device, cause the computing device to perform operations for communicating using embedded DNS messages, the operations comprising:

• selecting a query domain corresponding to a destination DNS server,
• wherein the destination DNS server is authoritative or an intermediary server for servicing DNS requests for the selected query domain;
• generating a message configured:
• to be parsed from a DNS lookup request by a destination DNS server as data distinct from a DNS domain of the DNS lookup request, and
• to be combined with the query domain to fit within a question portion of the DNS lookup request,
• wherein the message comprises an identification of a parsing algorithm, from among multiple possible parsing algorithms available to the destination DNS server, to use to extract data from the DNS lookup request;
• generating the DNS lookup request, the DNS lookup request comprising a question portion that includes a combination of the generated message and the query domain;
• and
• transmitting the DNS lookup request.

• wherein the destination DNS server is configured to determine, from among a plurality of parsing algorithms, a parsing algorithm corresponding to the generated message within the DNS lookup request.

A computing system for communicating using embedded DNS messages, the computing system comprising:

• a processor;
• a memory;
• a first component configured to select a query domain corresponding to a destination DNS server,
• wherein the destination DNS server is authoritative or an intermediary server for servicing DNS requests for the selected query domain;
• a second component configured to generate a message configured:
• to be parsed from a DNS lookup request by a destination DNS server as data distinct from a DNS domain of the DNS lookup request, and
• to be combined with the query domain to fit within a question portion of the DNS lookup request;
• a third component configured to generate the DNS lookup request, the DNS lookup request comprising a question portion that includes a combination of the generated message and the query domain;
• and
• a fourth component configured to transmit the DNS lookup request,
• wherein the destination DNS server is configured to determine, from among a plurality of parsing algorithms, a parsing algorithm corresponding to the generated message within the DNS lookup request,
• wherein the first component comprises computer-executable instructions stored in the memory for execution by the computing system,
• wherein the second component comprises computer-executable instructions stored in the memory for execution by the computing system,
• wherein the third component comprises computer-executable Instructions stored in the memory for execution by the computing system,
• wherein the fourth component comprises computer-executable instructions stored in the memory for execution by the computing system.
