To provide a communication device, a communication processing method, and a communication processing program capable of easily analyzing an error packet impossible to error correction.

A data receiver 2 acquires a packet addressed to itself through a communication network and a network hardware 8. The data receiver 2 detects whether there is an error in the acquired packet or not, and performs correction for the packet by requesting resending to a packet transmission source if an error is detected. The data receiver 2 outputs the packet to a packet analyzer 3 as an error packet, when it is impossible to correct the packet. The packet analyzer 3 extracts a transmission source IP address at an header in the error packet, generates an analysis result information indicative of an error frequency for each transmission source IP address, and stores the information at an analysis result storage 4. When an error frequency does not satisfy a predetermined criterion, an OS (Operating System) management 5 outputs an information indicative of a corresponding transmission source IP address to a display means 7.
