![]() ![]() Use the following display filter to show all packets that contain the specified IP in the source column: ip.src = 192.168.2.11 You might remember this from mathematics as a fancy way of illustrating “is not” or “not equal to.”Īs you can see we now see only the packets in the Packet List Pane that do not include 192.168.2.11.īut what if we wanted to see only packets that originated from a specific source IP? Filtering Specific Source IP in Wireshark This expression translates to “pass all traffic except for traffic with a source IPv4 address of 192.168.2.11 or a destination IPv4 address of 192.168.2.11.” Use the following display filter to show all packets that do not contain the specific IP in either the source or destination columns: !(ip.addr = 192.168.2.11) We can even do this inverse of this and filter out the specific IP Filtering Out (Excluding) Specific IP in Wireshark This expression translates to “pass all traffic with a source IPv4 address of 192.168.2.11 or a destination IPv4 address of 192.168.2.11.”Īs you can see the packets displayed in the Packet List Pane all contain 192.168.2.11 in either the source or the destination column. Use the following display filter to show all packets that contain the specific IP in either or both the source and destination columns: ip.addr = 192.168.2.11 Related: Wireshark User Interface (GUI) Overview Filtering Specific IP in Wireshark It’s also possible to filter out packets to and from IPs and subnets.īeyond that, you can use IP filters as both capture filters (only capture packets based on the filter) and display filters (filter the display of captured packets). We can filter to show only packets to a specific destination IP, from a specific source IP, and even to and from an entire subnet. With Wireshark we can filter by IP in several ways. One of the most common, and important, filters to use and know is the IP address filter. This amounts to a lot of data that would be impractical to sort through without a filter.įortunately, filters are part of the core functionality of Wireshark and the filter options are numerous. Unless you’re using a capture filter, Wireshark captures all traffic on the interface you selected when you opened the application. If you want to see multicast traffic just exclude it.The ability to filter capture data in Wireshark is important. The and not (eth.dst & 1) excludes any packet with the ethernet multicast bit set to true. There are other local ranges you might be using. Note that the above only excludes local IP traffic in the 192.168.* and 10.* IP range. Putting it all together, this filter will exclude local IP, IPv6, and broadcast/multicast packets: not (ipv6.dst = fe80::/10 and ipv6.src = fe80::/10) and Instead we know that the link-local IPv6 prefix is FE80::/10 so to exclude traffic that both originates from and is destined to this range we use this filter: ![]() It's 2022 and IPv6 is now a thing! IPv6 makes this trickier since you'll usually have multiple v6 addresses and they often change. If you only wanted to filter http traffic to and from that host, you could do this: not (host 192.168.5.22 and port 80) For example, to keep from capturing http and ssh traffic to/from any host and any packets to or from 192.168.5.22, not host 192.168.5.22 and not port 80 and not port 22 The downside is those packets are not captured if you later want to inspect them and you can't change the filter selected this way during a capture session. It makes the capture take less memory and disk by avoiding capturing packets you're telling it to ignore. ![]() While not strictly your question, I prefer to do filtering in the capture filter (double click the interface name in the capture-options dialog), whose syntax is exactly like tcpdump. Tcp.dstport != 80 suffers from a similar problem having tcp.dstport != 80 turns out to mean "match ONLY tcp traffic, but only tcp that is not dstport = 80" Here's a complete example to filter http as well: not ip.addr = 192.168.5.22 and not tcp.dstport = 80 For example, when connecting to 192.168.5.254 from 192.168.5.22, ip.addr != 192.168.5.22 doesn't match *.22 IP, it matches *.254 and thus the packet matches the filter expression. It might seem more logical to write it as ip.addr != 192.168.5.22, but while that's a valid expression, it will match the other end of the connection as not being the specific ip and still be true. ![]() You could also write it like so: not (ip.addr = 192.168.5.22) With the negative match like you have, you need both conditions to be true to filter off your IP, thus and instead of or. ![]()
