If you want to filter out all packets containing IP datagrams to or from IP address 1.2.3.4, then the correct filter is !(ip.addr = 1.2.3.4) as it reads “show me all the packets for which it is not true that a field named ip.addr exists with a value of 1.2.3.4”, or in other words, “filter out all packets for which there are no occurrences of a field named ip.addr with the value 1.2.3.4”. As an IP datagram contains both a source and a destination address, the expression will evaluate to true whenever at least one of the two addresses differs from 1.2.3.4. The reason for this, is that the expression ip.addr != 1.2.3.4 must be read as “the packet contains a field named ip.addr with a value different from 1.2.3.4”. Instead, that expression will even be true for packets where either source or destination IP address equals 1.2.3.4.
Not Equal gt, > Greater Than lt, < Less Than ge, > Greater than or Equal to le.Unfortunately, this does not do the expected. Programming Tutorial & Code Examples for Wireshark Filter Ip Address And. Then they use ip.addr != 1.2.3.4 to see all packets not containing the IP address 1.2.3.4 in it.
Not Equal to gt > Greater Than lt < Less Than ge > Greater than or Equal to le.Often people use a filter string to display something like ip.addr = 1.2.3.4 which will display all packets containing the IP address 1.2.3.4. Also refer to the WireShark Filter Syntax and Reference during this lab. You should see some geolocation information in either source or destination IP. Select any packet and expand its IP header. Using the != operator on combined expressions like eth.addr, ip.addr, tcp.port, and udp.port will probably not work as expected. Once you see the packets for the site, stop capturing. Wireshark allows you to string together single ranges in a comma separated list to form compound ranges as shown above.
