Ping

Test the reachability of a host and measure response time.

Uses a TCP-based ping (port 80) to test connectivity. ICMP ping is disabled for security reasons on shared hosting environments.

Understanding Ping

The Ping tool is a fundamental utility used to test the reachability of a host on an Internet Protocol (IP) network and measure the round-trip time for messages sent from the originating host to a destination computer.

How it works

Traditionally, ping operates by sending Internet Control Message Protocol (ICMP) Echo Request packets to the target host and waiting for an ICMP Echo Reply. However, in many shared hosting or restricted environments, raw ICMP sockets are disabled to prevent abuse (such as Ping of Death or Smurf attacks).

This platform utilizes a TCP Ping. Instead of sending ICMP packets, it attempts to open a standard TCP connection (typically on port 80 or 443) to the target. This provides a reliable indication of whether the web server is online and reachable from our network, while accurately measuring the TCP handshake latency.

Interpreting the Results

  • Status: Indicates whether the server successfully responded to the TCP connection request.
  • Latency: The time taken (in milliseconds) for the request to reach the server and the response to return. Lower latency means a faster connection.
  • Packet Loss: Since this is a single TCP probe, packet loss will typically register as either 0% (success) or 100% (failure/timeout).
