The display filter syntax to filter out addresses between 192.168.1.1 – 192.168.1.255 would be ip.addr=192.168.1.0/24 and if you are comfortable with IP subnetting, you can alter the /24 to change the range. However, if the addresses are contiguous or in the same subnet, you might be able to get away with a subnet filter. One time-consuming approach would be to literally type out all the addresses you want to filter on. In this video, I respond to a question from one of my readers who wanted to create a display filter for many IP addresses. The SSDP replies will be to muticast group address and should be captured if you run Wireshark in promiscuous mode. In either case, you will need to use a display filter to narrow the traffic down. Re: IP address of Camera through Wireshark. This reply contains the MAC address of the NIC of the default gateway. Even when you have a capture filter, it may be too generic. The host with the IP address of 192.168.1.1 (default gateway) will send a unicast reply to the source (PC host). Using Wireshark to get the IP address of an Unknown Host Running a remote capture with Wireshark and tcpdump Wireshark ‘no interfaces found’ error explained Identify hardware with OUI lookup in Wireshark Best Wireshark alternatives Get The Ultimate Wireshark eBook for FREE Learn everything there is to know about Wireshark. You may not know what to focus on when you capture packets, resulting in no capture filter. A display filter is configured after you have captured your packets. A capture filter is configured prior to starting your capture and affects what packets are captured. Note that in Wireshark, display and capture filter syntax are completely different. At this point you should be able to load a capture file, select StatisticsEndpoints, and see GeoIP information in any tab that contains IP addresses (IP, TCP, UDP, etc). Add the full path of each database directory, as shown below: Now, restart Wireshark. In this video, I review the two most common filters in Wireshark. Go to EditPreferencesName Resolution and select GeoIP database directories. One of the keys to being an effective network troubleshooter when using a protocol analyzer is the ability to see patterns, which is where filters come into play.
