We are going to use Wireshark as the Display Filter Wireshark (and tshark) have display filters that decode many different protocols – including DNS – and easily allow filtering DNS Since Wireshark doesn’t wait for DNS responses, the host name for a given address might be missing from a given packet when you view it the first time but be present when you view it subsequent times. Building on our previous discussion, we'll unravel more layers of DNS packets and flags, offering a comprehensive look at their significance and how they influence network communication. You can have access to the DNS details The DNS dissector has one preference: "Reassemble DNS messages spanning multiple TCP segments". Introduction Wireshark is a powerful open-source tool used for packet capture and analysis. You should see a larger set of records in this message; while DNS queries mostly serve to carry the query, DNS responses often return a set of useful information (see below for the As described in Section 2.
