## what is ping?
|
||
|
|
Ping is a network diagnostic tool that sends packets of data to a target host and measures the time it takes for the packets to be transmitted and received. The tool is used to test the connectivity of a network and to determine the round-trip time (RTT) for data packets to travel between two devices.

## Common use and commands:
|
||
|
|
The most common use of ping is to test whether a host is reachable over the network. To use ping, simply open a command prompt or terminal and type "ping" followed by the target host's IP address or domain name. The tool will send a series of ICMP packets to the target host and report the results, including the RTT and any packet loss.

|
|
|

|
|
- -c ---> Number of ping sent

TTL response from the ping might give some infromation about the operating system
|
||
|
|
- Linux ---> 64 or less
|
||

|
- Windows ---> 128
