Capture traffic to or from a range of IP addresses: So let's create a macro we will call IPAP (for IP Address Pair) and use the syntax replacing the addresses with $1 and $2: Now if I want to find a set of packets between an IP address pair, I simply type ${IPAP:17.248.185.174;192.168.1.114} in the display filter: The key here is that a semicolon separates the variables.

If, for example, you wanted to see all HTTP traffic related to a site at xxjsj you could use the following filter: tcp.port == 80 and ip.addr == 65.208.228.223 Wireshark has very powerful filtering features.

Wireshark Essential Training provides a solid overview of deep packet inspection by stepping through the basics of packet capture and analysis using Wireshark. then moves into deep packet analysis of common protocols such as TCP, IP, DHCP, and DNS. And within that we have a source and destination IP address.

Wireshark will show the warning “"!=" may have unexpected results” when you use it. People often use a filter string like ip.addr == 1.2.3.4 to display all packets containing the IP address 1.2.3.4. Then they use ip.addr != 1.2.3.4 expecting to see all packets not containing the IP address 1.2.3.4 in it. ip.addr == x.x.x.x Sets a filter for any packet that has x.x.x.x as the source or destination IP address.
