Task Net - Ping
The ping Task is used to test whether a particular host is reachable across an IP network. It works by sending ICMP “echo request” packets to the target host and listening for ICMP “echo response” replies. ping estimates the round-trip time in milliseconds.

Hostname
The IP address or host name of the server you want to PING.
Timeout in milliseconds
Timeout before the reply is considered too long. Produces error if longer than timeout. Default is 2000 ms (maximum 20000 ms).
TTL
Time to live (sometimes abbreviated TTL) is a limit on the period of time or number of iterations or transmissions in computer and computer network technology that a unit of data (e.g. a packet) can experience before it should be discarded. Default is 32. Use a value between 1 and 255.
