Domain name system, information processing method and apparatus of domain name system

A terminal device, comprising a processor and a non-transitory processor-readable medium having processor-executable instructions stored thereon, the processor-executable instructions comprising a plurality of modules, the modules comprising:

• a message generating module, configured to generate a domain name system query request that comprises identifier information of the terminal device;
• and
• a sending module, configured to send the domain name system query request to a recursive server, so that the recursive server forwards the domain name system query request with the identifier information of the terminal device to an authority server for query control;
• wherein the message generating module comprises:
• a first message generating unit, configured to generate a domain name system packet, and add the identifier information of the terminal device into a packet header of the domain name system packet;
• or
• a second message generating unit, configured to generate the domain name system packet, and add the identifier information of the terminal device into data information of the domain name system packet;
• wherein the packet header of the domain name system packet and the data information of the domain name system packet are not updated when the domain name system query request is forwarded by the recursive server.

An information processing apparatus of a domain name system, comprising a processor and a non-transitory processor-readable medium having processor-executable instructions stored thereon, the processor-executable instructions comprising a plurality of modules, the modules comprising:

• a receiving module, configured to receive a domain name system query request forwarded by a recursive server, wherein the domain name system query request comprises identifier information of a terminal device that sends the query request, and the identifier information of the terminal device is carried in a packet header of a domain name system packet or data information of the domain name system packet, wherein the packet header of the domain name system packet and the data information of the domain name system packet are not updated when the domain name system query request is forwarded by the recursive server;
• an obtaining module, configured to resolve the received domain name system query request to obtain the identifier information of the terminal device;
• and
• a control module, configured to exercise query control according to the identifier information of the terminal device;
• wherein the control module comprises:
• a first control unit, configured to control query rights of the terminal device according to the identifier information of the terminal device;
• or
• a second control unit, configured to statisticize number of times of query initiated by the terminal device according to the identifier information of the terminal device.

A domain name system, comprising a terminal device, a recursive server, and at least one authority server, wherein:

• the terminal device comprises a processor and a non-transitory processor-readable medium having processor-executable instructions stored thereon, the processor-executable instructions comprising a plurality of modules, the modules comprising:
• a message generating module, configured to generate a domain name system query request that comprises identifier information of the terminal device, and
• a sending module, configured to send the query request to the recursive server;
• wherein the message generating module comprises:
• a first message generating unit, configured to generate a domain name system packet, and add the identifier information of the terminal device into a packet header of the domain name system packet;
• or a second message generating unit, configured to generate the domain name system packet, and add the identifier information of the terminal device into data information of the domain name system packet;
• the recursive server is configured to receive the domain name system query request sent by the terminal device, and forward the query request to the authority server;
• and
• the authority server is configured to:
• receive the domain name system query request forwarded by the recursive server, wherein the domain name system query request comprises the identifier information of the terminal device that sends the query request;
• resolve the received domain name system query request to obtain the identifier information of the terminal device;
• and exercise query control according to the identifier information of the terminal device;
• wherein the authority server is specifically configured to control query rights of the terminal device according to the identifier information of the terminal device;
• or statisticize number of times of query initiated by the terminal device according to the identifier information of the terminal device;
• wherein the packet header of the domain name system packet and the data information of the domain name system packet are not updated when the domain name system query request is forwarded by the recursive server.
