Zusammenfassung:	Provided is a method of controlling the assignment of an IP address from a dual-stack home gateway (HGW). The method includes the following steps of: transmitting a neighbor discovery protocol (NDP) route solicitation (RS) message when flash information manifests Internet protocol version 6 (IPv6) or Null, wherein the flash information is information about a previous IP version for the operation of the home gateway; and performing a procedure of being assigned with an IP address in accordance with an IPv6 protocol when receiving an NDP router advertisement (RA) message in response to the transmission of the NDP RS message. Therefore, the present invention is capable of preventing IP addresses from being exhausted at an early stage. 듀얼 스택(Dual Stack) 홈게이트웨이(Home Gateway: HGW)에서 IP 주소를 할당받는 것을 제어하는 방법이 제공된다. 본 방법은, 플래쉬 정보가 IPv6(Internet Protocol version 6)를 나타내거나 Null인 경우 NDP(Neighbor Discovery Protocol) RS(Route Solicitation) 메시지를 송출하는 단계 - 상기 플래쉬 정보는 이전에 상기 홈게이트웨이가 운용되던 IP 버전에 관한 정보임 -, 및 상기 NDP RS 메시지의 송출에 응답하여 NDP RA(Router Advertisement) 메시지를 수신하는 경우 IPv6 프로토콜에 따른 IP 주소를 할당받기 위한 절차를 수행하는 단계를 포함할 수 있다.
