Hello There!

I have a question to answer please, I don't understand it, it is about data communication and networking "Wireshark"

Capture ICMP packets with “Wireshark” and analyze the results.

Capturing Basics and Filters

1_ Create a filter to show only HTTP traffic with destination port 80.

2_ Create a filter to exclude ARP and ICMP traffic from visualization.

3_ Create a filter to show DNS queries to a specific domain. TIP: Use the keyword contains to search a specific value in the payload.

I want to see screenshots please and outcomes,

Thanks!
