This avoids the contradiction (a = b and a != b) being true. In particular this means filter expressions with multi-value fields like ip.addr != 1.1.1.1 will work as expected (the result is the same as typing ip.src != 1.1.1.1 and ip.dst != 1.1.1.1). In addition to, the expression a != b now always has the same meaning as !(a = b). Now is possible to use the syntax a ~= b or a any_ne b to recover the previous (inconsistent with =) logic for not equal. In the latest Wireshark version, several changes have been made to the display filter syntax.

Now Wireshark 3.6.0 stable version has been released, so let’s take a look at what’s new. Therefore, you should only use Wireshark on networks where you have permission to inspect network packets. It captures network traffic on the local network and stores that data for offline analysis. On the other side, there are questions about the legality of Wireshark since it is a powerful packet sniffer. Probably, there isn’t a better way to learn networking than to look at the traffic under the Wireshark microscope. Government agencies, corporations, non-profits, and educational institutions use Wireshark for troubleshooting and teaching purposes. It captures packets in real time and display them in human-readable format.

Originally known as Ethereal, Wireshark has developed a reputation as one of the most reliable network protocol analyzers available out there. Recently, Wireshark has released a new version of its free and open-source packet analyzer, Wireshark 3.6.0, with all new features and protocols.
