The Enhanced Ping Tool is a significantly enhanced version of the classic network troubleshooting tool used to test whether a network device is reachable on an IPv4 or IPv6 network. The device can be anywhere, on your local area network or across the internet. Ping can also be used to determine response time from the device. TCP Ping takes this even further: the round-trip time is TCP latency for the service on the port you are contacting. ICMP Ping of an IPv6 address is supported.
Statistics including packet loss, minimum, average and maximum round-trip time and jitter are also shown. Graphing of the round trip time is shown in a separate window with image saving and printing.
This tool supports three different modes of Ping:

ICMP Ping mode sends ICMP Echo Request Packets like the command line tool built into Windows.
NetScanTools Pro has three modes of ICMP ping: MS ICMP mode (for IPv4) uses an operating system function to send and receive the ping packets. MS ICMPv6 mode (for IPv6) also uses an operating system funciton to send and receive the ping packets. The other mode for ICMP ping uses WinPcap as both the transmission and reception driver. The WinPcap dependent method allows sub-millisecond timing resolution for ping round trip times in contract to the MSICMP Ping method that has a resolution in the 10s of milliseconds.
ICMP packets are sometimes blocked by firewalls either between you and the target or on the target itself, so NetScanTools Pro has two other methods of 'pinging' a target: UDP and TCP.
NetScanTools Pro has two modes of UDP ping: UDP Socket Xmit mode uses an operating system function to send UDP packets and WinPcap to receive the responding ICMP packets. The second mode uses WinPcap to send the UDP packets and receive the responding ICMP packets. Both modes allow you to see sub-millisecond timing resolution for UDP ping.
TCP Ping mode uses TCP SYN packets to ping a target. The target typically responds with either TCP SYN/ACK or RST packets. The time it takes for a packet to get the target and back is the round trip time. TCP Ping uses WinPcap to send the TCP packets and receive the responding TCP packets. This mode allows you to see sub-millisecond timing resolution for TCP ping. You can use this tool to determine the latency for web servers or mail servers or just about any TCP service that is present on the target. This tool brings TCP Ping to the Windows platform.
