The .pcapng file format is related to captured data packets over the network. The Packet Capture Next
Generation file or the .pcapng file is a standard format for storing captured data.
PCAPNG files normally contain several blocks of data. These blocks of data contain different types of information that are useful in
capturing and analyzing network data, such as connection traffic.The blocks may consist of a section header block, interface
description block, enhanced packet block, simple packet block, name resolution block, and interface statistics block. These blocks
are necessary for recreating the data derived from the network to become readable information.
The PCAP Next Generation Dump File Format tends to replace files that are used with libCap. Currently, usage of .pcapng is declining
due to the emergence of other better viable formats used for storing captured network data.
