Abstract:
1. An information processing device comprising: a reception unit configured to receive an access request from a terminal, the access request including identification information identifying the terminal which sends the access request, wherein the reception unit receives an IPv6 packet as the access request, and wherein an authentication control unit uses a transmission source IP address set in the IPv6 packet received by the reception unit, as the identification information; a transfer unit configured to extract a second IPv4 packet, from a first IPv4 packet including, by additional encapsulation, the IPv6 packet including, by encapsulation, the second IPv4 packet including a transfer destination IP address, and transfer the second IPv4 packet to a device corresponding to the transfer destination IP address, wherein the reception unit allows a storage unit to store history information in which the transmission source IP address included in the IPv6 packet is associated with the transfer destination IP address included in the second IPv4 packet; and a control unit configured to acquire user information that is information about a user using the terminal based on the identification information included in the access request.
