Why this is useful
Shows how to distinguish capture filters from display filters, then progressively narrow a conversation without losing sight of the evidence.
Applicability
Version-specificThe 2021 interface is older. Use current Wireshark syntax alongside the demonstration.
Keep in mind
- Current set-membership filters use commas, for example tcp.port in {80, 443, 8080}; the video shows an older form.
- A capture filter of port 53 matches TCP as well as UDP. Encrypted DNS and TLS privacy features can hide names shown in older examples.
