Related: Wireshark Filter by IP ip.addr = 10.43.54.65 You may want to use ctrl+f to search this page because the list isn’t alphabetical. I suggest anyone interested in learning more about a filter to first play with the example given here in Wireshark and then hit up the official Wireshark Display Filter Wiki page.

I also chose to keep most examples brief since fully explaining each filter could fill a book. Now some of these searches do relate to each other, so there will be some repetition/overlap, but I decided to answer each query as it was searched to try and help as many people directly as possible. This gives us a list of the top 47 Filters that people are searching for! I dug up the top 500 Google search results relating to Wireshark Display Filters and compiled a list of all the unique Filter queries to answer.
