TCPing will send TCP probes to an IP address or a hostname specified
by you and prints the result.
It works with both IPv4 and IPv6.

TCPING uses different TCP sequence numbering for successful and
unsuccessful probes, so that when you look at the results and spot
a failed probe, understanding the total packet drops to that point
would be illustrative enough.

* Monitor your network connection.
* Determine packet loss.
* Analyze the network's latency.
* Show min/avg/max probes latency.
* Use the -r flag to retry hostname resolution after a predetermined
number of ping failures. If you want to test your DNS load
balancing or Global Server Load Balancer (GSLB), you should
utilize this option..
* Print connection statistics on Enter key press.
* Display the longest encountered downtime and uptime duration and
time.
* Monitor and audit your peers network.
* Calculate the total uptime/downtime when conducting a maintenance.
* An alternative to ping in environments that ICMP is blocked.
