Ping is one of the most used networking commands. In this article, you’ll learn what it is, how to use it, online ping tools, and some practical examples.

First of all, let’s see what ping is.

What is Ping?

Ping is a Terminal / Shell command utility used as a simple way to verify that a machine has internet access and can communicate with other computers or network devices.

Some of the functions of the ping command are :

  • Test network connectivity: local network, internet
  • Troubleshoot network interface card
  • Test DNS name resolution issues

Most operative systems like Windows, macOS, and Linux have Ping pre-installed, but we’ll head into the installation process through the article.

Maybe, you’ve seen ping in normal conversations, for example, “I’ll ping you once I’m done with the work”. In common language, ping simply means a message sent from a computer to another.

How does Ping work?

The basic idea of Ping is to ascertain connectivity between two devices. It works by the source device sending an ICMP echo request to the destination device and waiting for the echo reply.

Based on the tool, one gets information about packet loss, round trip time (RTT), and errors, if any. For a successful ping, the most important of these parameters is the RTT, indicating the total time it took the signal to travel up and down the source.

Usually, such tools send multiple Ping commands and give out the average RTT time, better known as Latency. It’s generally given in milliseconds; half of this value is known as Ping.

Ping Usage

To check you have ping installed, fire up a terminal (macOS, Linux) or command prompt (Windows), and type “ping –help”. In most cases, you should see something like this.

If you get a help section with a list of flags to use, you’re good to go. In some Linux distributions like Ubuntu, you may have trouble because ping isn’t installed by default. In Ubuntu, you can install ping with:

sudo apt install iputils-ping

Another way to test ping is installed in your system would be using which, that returns the path of any binary installed in your system:

which ping

# /usr/bin/ping  # My result

Now that you can use ping with no problem, it’s time to learn its basic usage.

The ping command connects to any host available, whether in your local network or over the internet. That host can be another computer, server, router, or even a printer.

Ping accepts one argument, which is the web or IP address you’re trying to connect to. For example, we’ll try to connect to

$ ping

Remember the “$” sign means we’re using a bash shell; in Powershell (Windows), it would be “>”. You should only copy the command and not the dollar sign.

After typing the above command, you should see something like the following:

PING ( 56(84) bytes of data.
64 bytes from ( icmp_seq=1 ttl=57 time=64.1 ms
64 bytes from ( icmp_seq=2 ttl=57 time=71.4 ms

First, it indicates the domain name we’re trying to connect to and its IP address within parenthesis. Then, it sends packets of bytes of data (usually 64) to the desired destination. To stop the ping command, just press Ctrl + C.

If you have a stable internet connection (which I’m sure you do since you’re reading this), you should get a message similar to the one below:

--- ping statistics ---
3 packets transmitted, 3 received, 0% packet loss, time 10192ms

This message shows the statistics of the pinging process you did to a domain name or IP address. As you can see, ping sent 3 packets of data, and it received all of them. That means both your internet connection and the hosting service that serves the IP address is working perfectly.

That same process occurs when you visit a web page, you (your browser) send packets of data with a request, the DNS (domain name service) translate the domain name to a real IP address, and then the host transmits the content of the page back to us. Of course, we’re skipping a lot of things, but this is just an explanation about a simple network interaction.

As a pro-tip, anytime you need a list of the available flags, you can call its manual page with man or the –help flag.

man ping
# Manual page
ping --help
# Help flag

IPv6 vs. IPv4

The world is running out of IP addresses, and as a result, we’re starting to implement IPv6 (Internet Protocol version 6).

Shortly explained, IPv4 is the core IP protocol that runs the web. It uses a 32-bit IP address, including a numeric-dot notation. For example, Google’s main IP address is has been here since 1981, and it’s the normal protocol we’re used to seeing.

On the other hand, IPv6 is another IP protocol that solves the problem of getting out of address. If IPv4 has up to 4.3 billion combinations, IPv6 could have 340 trillion trillion trillion IP addresses.

Here is an example of an IPv6 address: 2001:db8:3333:4444:5555:6666:7777:8888.

In other words, we’ll be transitioning to IPv6 addresses in the next few years because every IOF (internet of things) device and upcoming websites will need new addresses.

Ping already supports IPv6 addresses, and in some Linux distributions, you can find an exclusive command, ping6, for them.

However, the best way to ping an IPv6 address is using the -6 flag.

Here’s an example:

ping -6 2001:db8:3333:4444:5555:6666:7777:8888

If your network doesn’t support IPv6 yet, don’t worry. IPv6 adaption has been growing ginormously in recent years.

How to run a ping test online?

Ping only usage isn’t to determine if you’re able to reach a specific server, but also to get the latency (time that it takes ping to receive a response) of your request to a server. Online ping tools allow you to gather much more data about the ping processes like

On the other hand, if you’re having a bad time with your connectivity or just want to test out your server latency from different locations worldwide, an online Ping tool is your best choice.

Check out our free online ping tool, and perform pings from London, Mumbai, and Oregon. Using this tool, you’ll get important data like packet loss and the maximum and minimum time it takes to get a response from your server.

Command Examples

Let’s test and see some of the frequently used examples of this networking tool.

#1. Check Your Internet connection

This may seem obvious, but you can check you have access to the Internet by pinging (the action of using ping) a solid target host like


If you don’t get any response, it’s likely your Internet connection isn’t working properly.

#2. Send a Determined Amount of Pings

One problem you may encounter if you’re using a Unix machine is that ping sends packets of data indefinitely.  With the flag -c (count), you can specify the number of pings you want to make. For example, if you want to ping exactly three times, you would do.

ping -c 3

Note: This doesn’t occur in Windows where ping sends only 4 data packets

You can use this flag to send only a ping request and display the IP address of the destination you’re trying to reach.

ping -c 1

#3. Ping a Server Within an Interval

You can set an interval of seconds between sending each packet. The default interval is one second, but you can modify it with the -i flag.

ping -i 3

#4. Ping localhost

You can ping any IPv4 address; hence, you’re able to ping your localhost using either the localhost label or the IP address

ping localhost
# works fine
# works fine too

Ping won’t pass through a physical network interface but through a virtual loopback.

#5. Pinging a Broadcast

You can use the -b flag to send requests to a broadcast address. For example, you can ping all the devices in your local network with the following command.

ping -b

#6. Send a Specific Packet Size

Depending on your needs, you can change the packet size of your ping using the -s flag with the number of bytes you want to send.

ping -s 70

Note that some requests may not work if you send a big size packet.

#7. Flood ping

The -f flag sends ping requests as fast as your computer and network can. Since the minimal ping interval allowed to the user is 200ms, you must run it as a superuser with the command sudo.

ping -f
PING ( 56(84) bytes of data.
ping: cannot flood; minimal interval allowed for user is 200ms

sudo ping -f -c 1000
# Stop after 1000 pings
--- ping statistics ---
1000 packets transmitted, 1000 received, 0% packet loss, time 11158ms

As you can see, I used the count flag to stop sending requests once it hit 1000 times (notice how it only took 11 seconds).

Note: Be extremely careful using “flood ping” since you could cause a DoS (denial of service) to the server you’re pinging. The only situation you should use this is to test your server in high-intensity environments.
