- **Live Capture and Offline Analysis:**
Allows real-time packet capture for live network traffic analysis. Additionally, it can analyze saved capture files for offline inspection.
- **Filtering Capabilities:**
Powerful display filters help focus on specific packets, making it easier to pinpoint issues or analyze specific types of traffic.
- **Colorization and Packet Marking:**
Color-coded packet display and marking aid in visually identifying different types of packets and potential issues.
- **Protocol Hierarchy:**
Displays a hierarchical view of protocols used in a captured session, helping users understand the layers of communication.
- **Statistics and Conversations:**
Provides various statistics, including traffic summaries, protocol distribution, and conversations, giving insights into network behavior.
- **Export Options:**
Supports exporting captured data in various formats for further analysis or sharing, such as [CSV](../../files/CSV.md), [XML](../../files/XML.md), or plain text.
- **Display and Capture Filters:**
Allows the application of filters to limit the displayed packets or control which packets are captured, streamlining the analysis process.
