Destination Host Unreachable Error Message- Reasons and Solutions

The error message Destination Host Unreachable tells that the ping request from our computer cannot find the route to the destination IP address(destination host). It means, the Packet send from your computer reached the destination network successfully but the remote gateway failed to find the destination host. So the remote gateway sends an Echo message Destination host unreachable. What is the reason for getting Destination Host Unreachable error on your computer?

Whether it is related to the Operating System like Windows error and Linux error? Let us explain everything here.

Reasons For Getting Destination Host Unreachable Error Message

  1. The ping packet find the destination network but failed to find the destination host

  2. Packet Routing issue on Remote gateway

  3. Destination host might be down

  4. Connection issues


You will get this message if there is no route listed in the remote gateway for the packet sent from your computer to the destination host.

If there is no route available, it is impossible to find the destination host. Then your computer will receive an error message "Destination host unreachable" from the remote gateway.

Another reason is a faulty routing table. If the destination host is down at the time the packet sent, it may result in destination host unreachable error message.



Explanation of The Destination Host Unreachable Message

The error message "Destination Host Unreachable " tells that the ping request from our computer cannot find the route to the destination IP address(destination host).

It means, the Packet send from your computer reached the destination network successfully but the remote gateway failed to find the destination host.

So the remote gateway sends an Echo message Destination host unreachable.

It denotes there is no route listed in the remote gateway for the packet sent from your computer to the destination host.

It is impossible to find the destination host without a route, and your computer will receive the alert Destination host unreachable from the remote gateway.

If the destination host is down at the time the packet sent, it will also result in destination host unreachable error message.

ICMP error message Destination Host Unreachable

You may get Destination Host Unreachable message even if you ping to a host in the same subnet

When you ping to a host in the same subnet, your computer sends an ARP request for the MAC address of the destination device.

If the host does not exist, you will get destination host unreachable message because without completing the ARP request ICMP echo cannot be sent.

These are the possible reasons for Destination host unreachable error message and now let us check the troubleshooting steps.




Analyzing Destination Host Unreachable message

Microsoft Windows [Version 6.1.7600]

C:\corenetworkz>ping 4.2.2.2

Pinging 4.2.2.2 with 32 bytes of data:

Destination host unreachable.
Destination host unreachable.
Destination host unreachable.
Destination host unreachable.

Ping statistics for 4.2.2.2:
    Packets: Sent = 4, Received = 0, Lost = 4 (100% loss),

Why Am I Getting Destination Host Unreachable ICMP Error

When I ping to an IP address in a different network, ping packets reach the default gateway.

My default gateway sends the packet to the remote gateway.

So ping packet finally reaches the remote network. If the remote gateway fails to find the remote host, it sends an echo Destination host unreachable.


How to Resolve Destination Host Unreachable
The possible fix for the ICMP error message "Destination Host Unreachable" :
  1. Make sure that the local host configuration is correct
  2. Make sure Destination Computer/Device is up
  3. Disable the Firewall and check for the issue
  4. Perform a tracert to the destination IP and check where the problem lies


This tutorial explained how to fix one type of Destination Unreachable error. There is another type of similar error. To check the extended troubleshooting guide, click on the link below.
ICMP Echo Message Destination Net Unreachable


When the packet received at remote gateway and failed to find the remote host, you will receive ICMP Echo Destination Host Unreachable message.

However, if your computer didn't get a response from the remote gateway, the situation is different. The below link tells how to handle that situation.
Request Timed Out -Reasons and solutions


If you receive Destination Host Unreachable message, you know the issue lies with the remote gateway. If you get the transmit failed message on your PC, you may visit the link below.
ping Transmit Failed, Error Code 10045

Another transmit failed error message with different error code is:
Ping Transmit Failed Error Code 65


Since the message Destination host unreachable depends on the remote gateway, you cannot do much in your network or computer. It is independent of your PC Operating System. You can see this alert on both Windows and Linux Computer.

But if you receive hardware error instead of destination unreachable message, you can fix it by following the steps provided in the link below.

Thank you so much. I usually get Destination Host Unreachable error message while ping to my server IP. Now I understand thanks

I just solved this problem across part of a network in which half of the workstations would receive this error message when trying to PING the server and half could successfully PING the server. In my case (after looking everywhere else first) this turned out to be a defective network switch!

Pretty nice work mate, it would be better if you can post something which is limited to home networks and devices connected to it.
Thanks you have ignited good info in my mind...thanks

I remember this error message destination host unreachable but I completely forget when I saw it and what I was doing. Anyway it just disappeared from my computer without doing any. Now only I understand the real cause of this. Thanks..

I think this error is something with my Firewall. I did exactly the same steps you mentioned and now it is fine.

Thanks for your tutorial. Now I know why I am getting this.

Will I get Destination host error message if I unplug the computer right after sending the ping command?

To get Destination host unreachable message, ping request from your computer should reach remote gateway.

I have connected a pfSense box on WAN, directly to a simple Linksys router on LAN. When I ping the Linksys from the pfSense box I keep getting A RANDOM MIX OF "Destination Host Unreachable", timeouts and fast normal responses (3ms). How is that possible?

In order to check this issue, I request you to tell us the exact network diagram with IP addresses assigned to each devices.

@Devry85225,

Can you provide some more details ?

1. Are you able to go online from other devices using the same network?

2. Which device you are using and which OS?

Another cause for Destination Host Unreachable can be a corrupt Address Resolution Protocol (ARP) cache. Symptoms - Internet accessible but local file server not. Solution - Delete/Refresh the ARP cache. This site had good instructions https://techjourney.net/clear-delete-and-refresh-arp-cache-entry/

Cctv in ping showing destination host unreacheable from 5days and video loss in screen showing and in command promt cmd it showing media disconnected please help and reply with reason
Alex George said…
@ Unknown

It is difficult to answer your question without knowing your network diagram. However, from the information you provided, you need to check the connection between your CCTV and the router.

Media disconnected shows there is no connection to your CCTV. Is your CCTV connected to your network via cable or wireless?

How do you assign IP address to your CCTV?
