The Lazy Networker

Wireshark is a powerful network protocol analyzer that helps users capture and analyze network traffic. To make the most out of Wireshark, using the right filters is essential. Filters help narrow down the traffic to specific protocols, IP addresses, or ports, making it easier to analyze and troubleshoot network issues.

Filter by IP Address: ip.src == x.x.x.x or ip.dst == x.x.x.x to filter by source or destination IP address.

Filter by Port: tcp.port == 80 or udp.port == 53 to filter by specific TCP or UDP ports.

Filter by Protocol: http or dns to filter by specific protocols like HTTP or DNS.

Filter by TCP Flags: tcp.flags == 0x02 to filter by specific TCP flags, such as SYN or ACK.

Filter by Packet Length: frame.len > 100 or frame.len < 100 to filter by packet length.

Filter by Conversation: ip.src == x.x.x.x and ip.dst == y.y.y.y to filter by conversations between two specific IP addresses.

Filter by HTTP Requests: http.request.method == GET or http.request.method == POST to filter by specific HTTP request methods.

Filter by DNS Requests: dns.qry.type == A or dns.qry.type == AAAA to filter by specific DNS query types.

Filter by TCP Resets: tcp.flags.reset == 1 to filter by TCP reset packets.

Filter by Sequence Number: tcp.seq == 12345 to filter by specific TCP sequence numbers.
