<p>PURPOSE: An Internet protocol (IP) router and a method of allocating IP address are provided to form a communication device directly connected to an IP router and a communication device connected to another router into one sub network. CONSTITUTION: If an IP router is connected to a second router connected to a second WAN, an IP management unit (150) is allocated a preset number of IP addresses from the second router. A DHCP server unit (160) allocates the allocated IP addresses to at least one of communication devices that are connected to the IP router. The DHCP server forms a sub network between the communication devices connected to the IP router and at least one communication device connected to the second router. A first communication interface unit (110) performs a communication connection to a first WAN. A second communication interface unit (120) performs a communication connection to a second WAN. [Reference numerals] (110) First communication interface unit; (120) Second communication interface unit; (130) Third communication interface unit; (140) Detection unit; (150) IP management unit; (160) DHCP server unit; (170) Control unit</p> |
