What is ping in networking?

In any computer network i.e local network or internet, particular device or computer is identified by respective IP address and not by their names. Ping is used to check whether the particular IP address is available in network or not. When we Ping to the particular computer using it’s IP address, If we get a reply from particular IP address then we say particular IP address is available else we say Particular IP address is not available in network. On windows system or computer, the user has provision to enable or disable ping functionality. So sometimes what happens even though particular computer or IP address is available in the network but if ping functionality of that particular computer is disabled then you will get a reply as ping request timed out for the ping request and you would say, particular computer is not available in the network. So here we will see how to enable ping functionality.

Example of Ping:

Before we start enabling ping functionality or Echo Request, we will see an example of ping for better understanding. When you ping particular IP address and if the particular IP address is available in the network then you receive bytes, time and TTL in reply shown below. If Particular IP is not available in network then you receive reply as Request timed out or Destination host unreachable which is shown below. In below example IP address 192.168.1.65 is available in network and IP address 192.168.1.111 is not available in network.

Ping is not working or Ping request timed out

There are three situations where ping is not working or you get reply ping Request timed out or Destination host unreachable.

1)When host or destination IP does not exist.

2)Ping does not work when Echo Request is disabled.

3)Ping does not work when Firewall Incoming connections are blocked.

1)When host or destination IP does not exist

Ping does not work or you get reply destination host unreachable or request timed out when you try to ping IP address or host which does not exist which is shown below. So please check entered host is exist or not so that you can’t get reply as Destination host unreachable or Request timed out.
Ping is not working

2)Steps to Enable Ping functionality when Echo request is Disabled

So please follow the step to enable Echo request .
1)For a Better understanding of Ping. Two computers have taken here and ping functionality of computer whose IP address is 192.168.1.65 is disabled which is shown below. As ping functionality of computer whose IP address  192.168.1.65 is disabled when you ping to IP address 192.168.1.65, You will get a reply as Request Timed out and you would say device or IP address 192.168.1.65 is not available in the network but IP address 192.168.1.65 is available in the network. Only thing is that you are not getting a reply because ping functionality of the IP address 192.168.1.65 is disabled.

2)To enable ping functionality, please Press Windows+R of your computer.
3)Type firewall.cpl in Open field and Click OK.

4)Click on Advanced settings





5)First Click on Inbound Rules and then  check for File and Printer Sharing (Echo Request – ICMPv4 – In) which has Public Profile which is shown below.  On windows system Echo Request is responsible for sending Ping reply.  When your ping is not working means File and Printer Sharing (Echo Request – ICMPv4 – In) is not Enabled which is shown below.

6)To Enable ping functionality , please right click on File and Printer Sharing (Echo Request – ICMPv4 – In) which has Profile as Public and click on Enable Rule.

7)Congrats you have successfully enabled File and Printer Sharing (Echo Request – ICMPv4 – In) which is responsible for sending ping reply.

8)Now again pinging to IP address 192.168.1.65. As ping functionality of IP address 192.168.1.65 is enabled and you will get reply for ping request which is shown below.

3)Ping does not work when firewall is blocking the incoming connections

Ping does not work when firewall is blocking incoming connections so please follow the steps given in the below link to enable ping functionality.
Firewall allowing incoming connections
