Wireshark Filter by Destination IP

Introduction to Wireshark Filters

Wireshark is a powerful network protocol analyzer that allows users to capture and inspect network traffic. One of the key features of Wireshark is its ability to filter network traffic, which enables users to focus on specific packets of interest. In this article, we will explore how to use Wireshark to filter network traffic by destination IP address.

Understanding Wireshark Filters

Wireshark filters are used to specify which packets to display or capture. Filters can be based on various criteria, such as protocol, source or destination IP address, port number, and more. Wireshark supports two types of filters: capture filters and display filters. Capture filters are used to specify which packets to capture, while display filters are used to specify which packets to display.

Filtering by Destination IP Address

To filter network traffic by destination IP address in Wireshark, you can use the following syntax: ip.dst == . For example, to filter traffic destined for the IP address 192.168.1.100, you would use the following filter: ip.dst == 192.168.1.100.

📝 Note: You can also use the dst host filter, which is equivalent to ip.dst ==. For example: dst host 192.168.1.100

Using Wireshark Filters

To apply a filter in Wireshark, follow these steps: * Start Wireshark and begin a new capture or open an existing capture file. * Click on the Analyzer menu and select Display Filters. * In the Display Filter window, enter your filter syntax (e.g., ip.dst == 192.168.1.100). * Click Apply to apply the filter.

Additional Filter Examples

Here are some additional examples of Wireshark filters: * ip.src == : Filter by source IP address. * tcp.port == : Filter by TCP port number. * udp.port == : Filter by UDP port number. * http: Filter by HTTP protocol.

Table of Common Wireshark Filters

Filter Syntax	Description
ip.dst ==	Filter by destination IP address
ip.src ==	Filter by source IP address
tcp.port ==	Filter by TCP port number
udp.port ==	Filter by UDP port number
http	Filter by HTTP protocol

In summary, Wireshark filters are a powerful tool for analyzing network traffic. By using the ip.dst == filter, you can focus on traffic destined for a specific IP address. With practice and experience, you can become proficient in using Wireshark filters to troubleshoot and analyze network traffic.
