This is where a high-quality network analyzer comes into play.Īny typical network analyzer will capture and display packets, providing basic packet information such as time of capture, source & destination MAC address, source & destination IP address, Layer 4 protocol information (TCP/UDP flags, ports, sequence/acknowledgement numbers) and the data payload.
These methods are usually enough to diagnose simple problems, but are clearly inadequate when dealing with complex network problems. These tests usually involve checking the source (Client or Network device) IP address, Gateway, DNS server, Nslookup and performing a few ICMP Echo Requests (aka Ping) to verify connectivity with the local network and destination IP. When dealing with network problems, engineers usually follow standard tests to try to identify the source of the problem and make any necessary corrections. A Network Analyzer allows users to capture network packets as they flow within the enterprise network or Internet.Įngineers usually make use of Network Analyzers to help uncover, diagnose and fix network problems, but they are also used by hackers to obtain access to sensitive information and user data.įEATURES OFFERED IN HIGH-QUALITY NETWORK ANALYZERS Network Analyzers, also known as Packet Sniffers, are amongst the most popular network tools found inside any Network Engineer’s toolkit.
