Deep Packet Inspection (DPI; also complete packet inspection or Information eXtraction, IX) stands for a method of monitoring and filtering network packets. In contrast to the classic packet filter, which only checks the header part of the data packet, deep packet inspection searches the header and data part of the data packet.
This usually looks for specific characteristics such as protocol violations, viruses and spam. This is what the DPI statistics of the Unifi Dream Machine Pro SE look like:
