Abstract: Embodiments of the present invention provide an Internet address information processing method, apparatus and an Internet system. The method includes: receiving, by a first leaf node, a query request message containing an IP address to be queried sent by user equipment, and performing query or sending a query request to an intermediate layer node; obtaining, by the intermediate layer node, an IP address of a second leaf node according to a prefix of the IP address to be queried to send the query request message to the second leaf node; and finally, sending, by the second leaf node, address information about the IP address after receiving the query request message. Embodiments of the present invention further provide corresponding apparatus and system. The method, apparatus, and system provided by the present invention are capable of implementing real-time query for address information about IP addresses.

Abstract: Embodiments of the present invention provide a domain name system as well as an information processing method and apparatus of the domain name system. The information processing method includes: receiving a domain name system query request sent by a recursive server, where the domain name system query request includes identifier information of a terminal device that sends the query request; resolving the received domain name system query request to obtain the identifier information of the terminal device; and exercising query control according to the identifier information of the terminal device. In the domain name system as well as the information processing method and apparatus of the domain name system, the domain name system query request carries the identifier information of the terminal device that sends the query request, and therefore, effective control is exercised on the information query actions of the terminal device in the domain name system.
