PacketTrap (http://www.PacketTrap.com) Ping Scan is a FREE utility that sends ICMP ECHO requests across a network and rapidly builds a spreadsheet of responding nodes. DNS lookup information may optionally be provided by Ping Scan for each responding address. Ping Scan is part of the pt360 Tool Suite. The pt360 Tool Suite features a unique centralized dashboard and includes network reporting, diagnostics and monitoring from a single intuitive interface. The solution contains network discovery, network inventory, Cisco Configurator, Switch Port Mapper, NetFlow Listener, TFTP server, SNMP, WMI, Port Scan, DNS Audit, Trace Route, Syslog Server, Ping and supports open source tools (i.e. Nagios, MRTG, Cacti), SaaS (Salesforce.com), and virtual servers. pt360's dataflow capabilities automatically pass information between tools so network engineers can pinpoint problems faster and easier than using dissimilar point tools.
