Quit without Saving to discard the captured traffic. Close Wireshark to complete this activity.Click Clear on the Filter toolbar to clear the display filter.

Observe that the Packet List Pane is now filtered so that only traffic to (destination) or from (source) IP address 8.8.8.8 is displayed.Type ip.addr = 8.8.8.8 in the Filter box and press Enter.Use ping 8.8.8.8 to ping an Internet host by IP address.Īctivity 2 - Use a Display Filter.YouTube: Wireshark 101: Display Filters and Filter Options, HakTip 122Īctivity 1 - Capture Network Traffic.These activities will show you how to use Wireshark to capture and filter network traffic using a display filter. It is generally used for hiding traffic to analyze the specific type of traffic. This type of filter can be changed while capturing traffic. Display Filters: This type of filter is used to reduce the packets which are showing in Wireshark. However, the '& 0xffffff00' expression masks off the fourth byte.Wireshark is a free and open source packet analyzer used for network troubleshooting and analysis. Capture traffic to or from a range of IP addresses: net 192.168.0.0/24. Unfortunately, you want to examine three bytes, but you can only put 1, 2, or 4 after the colon, so three is not a valid value. In the capture filter expressions 'ether' and 'ether', 0 and 6 are the starting bytes for the destination MAC address field and the source MAC address field respectively, and 4 is the number of bytes to examine. To capture packets where either the source or destination MAC address starts with 00:0C:22: But if you know where in the MAC address field those three bytes will be, you can use a byte-offset capture filter. You probably can't create a capture filter for MAC addresses containing 00:0C:22 anywhere in the MAC address fields. You said, 'I want to capture all traffic from devices with MAC address containing 00:0C:22.'
