How to Ping an Ip Address

How to ping an IP address

You can not simply ping in Java as it relies on ICMP, which is sadly not supported in Java

Use sockets instead

How to ping an IP Address in golang

As @desaipath mentions, there is no way to do this in the standard library. However, you do not need to write the code for yourself - it has already been done:

Note, sending ICMP packets requires root privileges

Pinging servers in Python

This function works in any OS (Unix, Linux, macOS, and Windows)
Python 2 and Python 3

EDITS:

By @radato os.system was replaced by subprocess.call. This avoids shell injection vulnerability in cases where your hostname string might not be validated.

import platform    # For getting the operating system name
import subprocess  # For executing a shell command

def ping(host):
    """
    Returns True if host (str) responds to a ping request.
    Remember that a host may not respond to a ping (ICMP) request even if the host name is valid.
    """

    # Option for the number of packets as a function of
    param = '-n' if platform.system().lower()=='windows' else '-c'

    # Building the command. Ex: "ping -c 1 google.com"
    command = ['ping', param, '1', host]

    return subprocess.call(command) == 0

Note that, according to @ikrase on Windows this function will still return True if you get a Destination Host Unreachable error.

Explanation

The command is ping in both Windows and Unix-like systems.

The option -n (Windows) or -c (Unix) controls the number of packets which in this example was set to 1.

platform.system() returns the platform name. Ex. 'Darwin' on macOS.

subprocess.call() performs a system call. Ex. subprocess.call(['ls','-l']).

How to ping an IP address from a VueJS application?

Ping is a node.js module not supported in the browser. This module would need to run server-side.

This could be accomplished us axios where you issue a GET call to the url and if you get a 200 back that indicates a successful call. This could also be accomplished using $ajax.

axios example

const response = await axios.get('https://api.github.com/users/mapbox');

if (response.status === 200) {
  console.log('success'
}

PYTHON PING IP ADDRESS WITH RESULTS

If you need to capture the output, or just don't like the way you are doing it currently then you could capture stdout and check the output for a failure string. You can capture stdout like this:

def ping(host):
    param = '-n' if platform.system().lower()=='windows' else '-c'
    command = ['ping', param, '1', host]

    result = subprocess.run(command, stdout=subprocess.PIPE)
    output = result.stdout.decode('utf8')
    if "Request timed out." in output or "100% packet loss" in output:
        return "NOT CONNECTED"
    return "CONNECTED"

print(ping(ip_addr))

Ping multiple computers through Excel and have IP addresses in a separate column

This worked for me

Sub temp()
    Set WshShell = CreateObject("WScript.Shell")
    RowCount = Worksheets("Sheet1").UsedRange.Rows.Count

For i = 1 To RowCount
    Url = Worksheets("Sheet1").Cells(i, 1).Value
    cmd = "ping " + Url
    Set WshShellExec = WshShell.Exec(cmd)
    result = WshShellExec.StdOut.ReadAll
    Worksheets("Sheet1").Cells(i, 2).Value = getIP(result)
    
    If (InStr(result, "Received = 4")) Then
        Worksheets("Sheet1").Cells(i, 3).Value = "Online"
    End If
Next
End Sub

Function getIP(result)
    ip = Split(result, vbNewLine)(1)
    startIndex = InStr(ip, "[") + 1
    endIndex = InStr(ip, "]")
    getIP = Mid(ip, startIndex, endIndex - startIndex)
End Function
