PCAP Explorer: analyze a PCAP file online and map your traffic PCAP Explorer is a free network analysis tool that parses .pcap and .pcapng capture files and shows where your packets are going on an interactive world map, alongside a traffic timeline and a list of top talkers. It reads IPv4 and IPv6, detects the busiest host in a capture automatically, and needs no account or install. This page needs JavaScript to run the analyzer. Built by Jason Eissayou.
