Here is our list of the best free NetFlow Analyzers: With a NetFlow analysis tool, an administrator can see how efficiently data is transferred across a network without relying on the large volumes of stored data that regular packet capture procedures create. It is in this area that NetFlow analyzers are worth their weight in gold. So much of an enterprise-grade service’s reliability rests on its bandwidth performance. Cell (3G, LTE) network information such as IP address, signal strength, network provider, MCC, MNC, etc.For some time, NetFlow analysis has been one of the core strategies relied on by IT administrators to conduct real-time network monitoring. Wifi network information such as SSID, BSSID, IP address, HTTP proxy, subnet mask, signal strength, etc. Default gateway, external IP (v4 and v6), DNS server Support for A, AAAA, SOA, PTR, MX, CNAME, NS, TXT, SPF, SRV records Functionality similar to nslookup or dig Whois of domains, IP addresses and AS numbers Description of the known open port services Detection of closed, firewalled, and open ports Fast, adaptive algorithm for scanning the most common ports or user specified port ranges Support of both for IPv4 and IPv6 (selectable) Round trip delay including IP address and hostname for every network node NetBIOS, mDNS (bonjour), LLMNR, and DNS name where available Vendor name, IP, and MAC addresses of all discovered devices Fast and reliable detection of all network devices BSSID (router MAC address), manufacturer, WPS support Both graphical and textual representation showing network channels and signal strengths Everything works with both IPv4 and IPv6. Finally, it shows all neighbouring wi-fi networks together with additional details such as signal strength, encryption and router manufacturer to help discovering the best channel for a wireless router. Further, Network Analyzer contains standard net diagnostic tools such as ping, traceroute, port scanner, DNS lookup, and whois. It is equipped with a fast wifi device discovery tool, including all the LAN device's addresses, manufacturers and names. Network Analyzer can help you diagnose various problems in your wifi network setup, Internet connectivity, and also detect various issues on remote servers thanks to the wide range of tools it provides.
