On this page you can online ping tool
for remote domain or hostname, IP address.
Domain/hostname/IP address ping going with 8 packages starting from current ping server, after end displaying info.
The IP address 127.0.0.1 is set by convention to always indicate your own computer.
Therefore, a ping to that address will always ping ip of yourself and the delay should be very short.
This provides the most basic test of your local communications.
Ping domain services also can be used for ddos attacks because there is option that allow do not wait ping answer and just flood IP address.
In theory, all TCP/IP-based network equipment should respond to an ECHO_REQUEST by returning the packet to the source, but it's working not in all cases.
Delay time do not display connection speed to this server, there is lots of ISP with hight ping and fast download/upload speed, and there are lots of ISP with low ping delay - but slow network.
Example - 10 mbit network can have more fast ping then some 100mbit network.
Ping it's one of perfect way to connection and route diagnostic. There are lots of situation when destination server answering to slow... How to know - it's connection issue or server overloaded?
As usualy server overload (or server freezing) continue to ping fine, becuase ping working on network card hardware level, but if server is slow and ping slow too - it's connection problem.
Notice: Some remote servers do not allow to ping they (due firewall settings), that is why ping of some online server (ping some remote ip address) can be fail (it's not issue of our service).
