To display traffic from a specific IP address: ip.addr. 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”. Once you start capturing traffic, you can then refine your capture results by using a display filter. 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”. (Ideally, the Wireshark display filter validation could be improved to detect this and turn the expression red instead of green.) ip.address 153.11.105.34 or 153.11.105. Instead, that expression will even be true for packets where either source or destination IP address equals 1.2.3.4. Unfortunately, this does not do the expected. IP address Filter Jika kita ingin menangkap hanya packet yang dikirim dari IP tertentu saja, ip.src 80.80.80.80 Atau IP address tujuan tertentu saja, ip.dst 80.80.80.80 atau jika kita tidak peduli arah yag dituju, ip.addr 80.80.80. Then they use ip.addr != 1.2.3.4 to see all packets not containing the IP address 1.2.3.4 in it. 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. Using the != operator on combined expressions like eth.addr, ip.addr, tcp.port, and udp.port will probably not work as expected. Wireshark allows you to string together single ranges in a comma separated list to form compound ranges as shown above. Source Source address of the packet, could be an IP or MAC address.
