What tcpdump parameter was used to produce the output on lines 2 and 3 shown below?

The -n flag suppresses hostname and port name resolution, displaying raw IP addresses and port numbers instead of DNS names - it does not alter how packet payload data is rendered.

The -r flag reads packet data from a previously saved .pcap file rather than a live interface, affecting the data source but not the display format of packet contents.

The -A parameter instructs tcpdump to print each packet in ASCII format, rendering the packet payload as readable text. This is commonly used to inspect plain-text protocol traffic such as HTTP headers and bodies, which would produce the type of readable multi-line output described in the question.

The -i flag specifies which network interface to capture traffic from (e.g., -i eth0) and has no effect on how the captured packet data is formatted or displayed.
