Abstract: The present disclosure relates to a device and method for transmitting and receiving data to and from a terminal in a wireless communication system. The method of operating the terminal in the wireless communication system may include the processes of comparing pre-stored domain name service (DNS) cache information with DNS inquiry information in a DNS inquiry if the DNS inquiry on a host is received from a uniform resource locator (URL) protocol handler, and transmitting internet protocol (IP) address information corresponding to the host to the URL protocol handler according to a compared result.
