System and method for auto-configuration and discovery of ip to mac address mapping and gateway presence

In order to offer the node accessed to a fixed network, two or more mobile radio user terminals (102*1*102*n), In the radio peer to peer ad hoc routing network (100) which consists of a fixed network (104) which has two or more access nodes (106*1*106*n), The system and method of processing the broadcasting network request which carries out automatic constitution of the mapping to a MAC Address from an IP address, and discovers existence of a gateway are indicated. A hash function is applied to 6 bytes of hardware (MAC) address, and it asks for the specific portion of the IP address of a node by calculation. This specific portion is added to the notice of routing, and it is constituted so that this may spread actively to other network nodes. An other broadcasting type demand, and DHCP and an ARP demand are processed by the local network stack of a node, without needing broadcasting transmission through a radio channel.
