It counts the number of hops and measures how long it takes a packet to travel between addresses. NameLookup and NameScan resolve IP addresses into names for single IP addresses or a range of addresses. Port Scanner looks for accessible Transmission Control Protocol and User Datagram Protocol ports at a remote IP address. A Service Scanner tool can test a range of IP addresses to discover which ones are running services such as File Transfer Protocol or Telnet. Rounding out the suite are Finger, Whois and Throughput tools.
Finger finds information associated with an e-mail address.
Whois looks for Internet directory information on whois servers, such as whois.internic.net. You can set up filters based on physical or logical addresses, protocols, contents and error conditions. The Throughput tool asks for a uniform resource locator for a Web or FTP server, and then it pulls up that site. In doing so, it counts the number of items loaded, file sizes, length of download and throughput speed. You can only license EtherPeek for individual machines, so using it to troubleshoot a WAN environment would require buying as many copies as you have LANs.
