The first filter uses "not ip.dst" to include all non-IP packets and then lets "ip.dst ne 224.1.2.3" filter out the unwanted IP packets. The second filter also negates the implicit existance test and so is a shorter way to write the first. 常用命令# 选出需要ip地址# IPv4 addresses ...

The expression “a != b” now always has the same meaning as “!(a == b)”. 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”)....
use "tr.rif". Think of a protocol or field in a filter as implicitly having the "exists" operator.ComparisonoperatorsFields can also be compared against values. The comparison operators can be expressed either through English-like abbreviations or through C-like symbols: eq, == Equal ne, !=...
2. DISPLAY FILTERS: The display filter is used to search inside captured data obtained with a capture filter. Its search capabilities are more extended than those of the capture filter and it is not necessary to restart the capture when you need to change your filter....
