# Revision history [back]

Yes, this is possible to do. The easiest way is to right-click on the column heading and de-select Resolve Names.

You can also manually edit your preferences file and change the behavior too:

• Open your preferences file.
• Search for gui.column.format
• Modify the LS Type entry, replacing R with U
• Restart Wireshark

The R is for Resolved; the U is for Unresolved.

One feature that's lacking is the inability to change this from the Edit -> Preferences -> Columns dialog. A Wireshark enhancement bug should probably filed for this.
