These filters and its powerful filter engine helps remove the noise from a packet trace and only see the packets of interest.ĭisplay filters allow us to compare fields within a protocol against a specific value, compare fields against fields and check the existence os specific fields or protocols.īellow you can find a small list of the most common protocols and fields when filtering traffic with Wireshark. There over 242000 fields in 3000 protocols that let you drill down to the exact traffic you want to see. Refer to the wireshark-filter man page for more information about the slice operator and Wireshark display filters in general.Wireshark’s most powerful feature is it vast array of filters. For example, if the source address was 50.xxx.xxx.100 and the destination address was .152, then the packet would still match the filter, as the 1st byte of the source address would match as well as the last byte of the destination address. Unfortunately, this doesn't work reliably because it will actually match either the 1st byte of either the source or destination addresses as well as the 4th byte of either the source or destination IP addresses.

Note that you might be tempted to use a simpler filter such as: ip.addr=32 & ip.addr=98 This filter also avoids any potential problems with whether name resolution is enabled or not, as ip.host isn't necessarily guaranteed to match "\.152$" if name resolution is enabled.

The filter uses the slice operator to isolate the 1st and 4th bytes of the source and destination IP address fields. Those values, 32 and 98 are hexadecimal values for 50 and 152, respectively.
