Claim Text:
1. An image forming apparatus comprising: a communication interface part that receives information request data from a network and transmits response data for the information request data to the network, in a normal mode and in a standby mode, wherein the information request data includes a request of Address Resolution Protocol (‘ARP’) or Simple Network Management Protocol (‘SNMP’); a normal mode response data making part that makes the response data in the normal mode, wherein: if the information request data includes one of an ARP request and a Reverse Address Resolution Protocol (‘RARP’) request, the response data includes address information having one of an IP address and MAC Address for the image forming apparatus: if the information request data includes a SNMP request, the response data includes SNMP response information having one of a SNMP-Get response and a TRAP; and the SNMP response information includes items of Object Identifier (‘OID’) and data, the OID being an identifier that is attached and distinguishes an object of each management information stored in Management Information Base (‘MIB’) for SNMP, and the data including items of type and data value; a recursive response request part that recursively transmits information request data for requiring information of other response data to the normal mode response data making part in the normal mode, wherein: the recursive response request part requires the information of the other response data when the response data including a previously-defined specific kind of information is made by the normal mode response data making part as corresponded to the information request data from the network; the specific kind of information includes an IP address and a MAC Address; and the information request data recursively transmitted includes a GetNext request of SNMP; an information storing part that accumulates the information of the other response data made by the normal mode response data making part corresponding to the information request data recursively transmitted by the recursive response request part in the normal mode; a standby response part that: extracts information required for a standby mode response from the response data, wherein the information required for the standby mode response includes address information and the SNMP response information; and stores the information required for the standby mode response in memory included in the image forming apparatus; wherein, the recursive response request part: determines, if a notice of the address information being memorized is performed, whether or not there is a sufficient area to store the SNMP response information in the memory; the recursive transmission performed by recursive response request part occurs following a determination there is the sufficient area to memorize the SNMP response information in the memory, wherein the information request data includes a SNMP-GetNext request that requires the information of the other response data; and a standby mode response data making part that makes the response data in the standby mode from information accumulated by the information storing part.
