Wireshark is a data capturing program that "understands" the structure (encapsulation) of different networking protocols. It can parse and display the fields, along with their meanings as specified by different networking protocols. Wireshark uses pcap to capture packets, so it can only capture packets on the types of networks that pcap supports.
PCAP-over-IP is a method for transmitting captured network traffic through a TCP connection. [1] The captured network traffic is transferred over TCP as a PCAP file in order to preserve relevant metadata about the packets, such as timestamps.

A capture file saved in the format that libpcap, WinPcap, and Npcap use can be read by applications that understand that format, such as tcpdump, Wireshark, CA NetMaster, or Microsoft Network Monitor 3.x. The file format is described by Internet-Draft draft-ietf-opsawg-pcap; [5] the current editors' version of the draft is also available. [6]
DPI allows service providers to "readily know the packets of information you are receiving online—from e-mail, to websites, to sharing of music, video and software downloads". [14] Policies can be defined that allow or disallow connection to or from an IP address, certain protocols, or even heuristics that identify a certain application or ...
