Wireshark doesn't limit the way you can view the data in the interface. In fact, in this last section, we'll see the many options to view the captured packets:

• Resize Layout: This option, when selected will resize the visible panels so they have a uniform appearance.
• Resize Columns: Much like you can resize the columns in Excel to autofit to their contents, Resize Columns will adjust the columns, so the contents fit. When using IPv4, the columns may adjust nicely, but using IPv6 takes up much more space and may not give you an optimal view.

If you are a developer, the next section outlines what is available behind the scenes to allow Wireshark to dissect and display the various protocols:

• Internals: The Internals menu choice provides advanced options that include the following:
  • Conversation Hash Tables: This shows the address and port combinations that identify each conversation, as shown here:

Select a single packet and then click Conversation Hash Tables to bring up the information.

• • Dissector Tables: This provides tables of relationships among subdissectors, as shown in the following example:

• • Supported Protocols: This will bring up an extensive list of all currently supported protocols and the protocol fields, along with the suggested filter and a brief description.

• Show Packet in New window: At times, you may want a single packet in its own window as a popup. This option may be ideal for training or to show a single packet, but doesn't offer any functionality—meaning, you can't right-click or use any shortcuts while in that window.
• Reload: This option will reload the capture, which will freshen the capture file. This can be helpful if you have marked packets and manipulated the file already, and you want a fresh start with the file.
