Apply as Column is a handy feature that allows you to turn any field from a packet into a custom column in the packet list. This makes it much easier to track specific values across all packets, such as IP addresses, ports, protocol flags, or even custom protocol fields.

It’s especially useful when you’re analyzing patterns, comparing values between packets, or just want to keep an eye on something that’s not shown by default.

How to Use “Apply as Column”

To create a column from any packet field:

1. Select a packet
2. In the Packet Details pane, right-click on the field you want
3. Choose:

Apply as Column

A new column will instantly appear in the packet list, showing that field’s value for every packet where it exists.

Example

Right-clicking on the http.request.method field and applying it as a column will show values like GET, POST, or HEAD for all HTTP requests in your capture.
