Abstract: A device and method for allocating the same Internet protocol (IP) address to all information terminals or hosts connected to a specific local network, which allows the hosts in the local network to gain access to the Internet while the hosts share a single IP address. The device includes a dynamic host configuration protocol (DHCP) client, a local access point, and a DHCP server spoofer. The DHCP client is allocated an IP address through a DHCP message communication with an Internet service provider. The Internet service provider includes a DHCP server for allocating IP addresses to the hosts and an Internet access gateway. The local access point includes a hardware address port translation (HAPT) module and a local IP address translation (LIAT) module.

Abstract: A PPPoA (point-to-point (PPP) over asynchronous transfer mode (ATM)) spoofing function utilizing an asymmetric digital subscriber line (ADSL) modem to form a single network between a client PC and a network access server (NAS) by allowing the ADSL modem to make a PPP connection to the NAS when the client PC is booted, by allowing the NAS to transmit Internet protocol (IP) configuration information, including a global IP address, to a DHCP server of the ADSL modem through a PPP Internet Protocol control protocol (IPCP), and by allowing the ADSL to transfer the IP configuration information received from the NAS to the client PC, thereby forming a bridge by the ADSL modem between the client PC and the NAS to enable IP packets to be transferred between the client PC and the NAS.

Abstract: A digital subscriber line modem of a PPPoE method has a dynamic host configuration protocol (DHCP) spoofing server which can make it possible to connect to said Internet by booting the client terminal, without installing a PPPoE driver in a client terminal, and a system thereof, and a method of connecting to the Internet using the same.
