Filter Expression	Description
ip.addr == 192.168.1.100	Filters traffic to or from the IP address 192.168.1.100
tcp.port == 80	Filters traffic using TCP port 80 (HTTP)
udp.port == 53	Filters traffic using UDP port 53 (DNS)
http.request.method == "GET"	Filters HTTP GET requests

Understanding how to create and apply these filters is a fundamental skill for efficient network troubleshooting using this versatile tool. Properly configured filters can save administrators significant time and effort in identifying and resolving network problems.
