  • Domain name system address configuration method and apparatus
    Patent number: 9210121
    Abstract: A method and an apparatus for configuring Domain Name System (DNS) address of a terminal are provided. The DNS address configuration method of a terminal according to an exemplary embodiment of the present invention includes establishing a connection with a network, requesting the network for the DNS address, determining whether the DNS address is successfully received from the network, and configuring, if the DNS address is not successfully received, the DNS address of the terminal with an auxiliary DNS address stored in the terminal. The DNS address configuration method and apparatus according to an exemplary embodiment of the present invention is advantageous to configure the DNS address of a terminal even if the terminal fails to receive the DNS address from the network or if the received DNS address is erroneous.
