In the response packet, observe the swapping of IPs between source and destination. When you struggle to type the appropriate filter, you waste valuable time. For a capture filter, you'd use a very similar construct, such as: (ip[12]=50 && ip[15]=152) || (ip[16]=50 && ip[19]=152) Refer to Section 3.1 of RFC791 for the IPv4 header format (and offsets to the relevant source and destination IP address fields) and to the pcap-filter man page for more information on capture filters. In this case, the dialog displays host names for each IP address in a capture file with a known host. The netmask is used only when deciding how to deal with routers and broadcast addresses, and isn't sent over the wire at any point.

Wireshark captures packets through the network interface of the computer that it is installed on. The software can process complex data from hundreds of protocols on most network types, organizing it into data packets. Alternatively, you can highlight the IP address of a packet and then create a filter for it. However i do like the idea of letting the shark create a 'ip summary' first then automate some unix search power on those lists .. ..
