Understanding Ping Responses,Destination unreachable,Request timed out,Reply
Here we are going to see ping responses network unreachable,request timed out,success with a simple topology by adding static route on each router step by step.
Step 1:Create a topology like this
Step 2:Routers only knows directly connected network,there is no static route added.Now, ping default gate way 10.0.0.1 from Host 10.0.0.10. we will get reply from 10.0.0.1.Because router knows 10.0.0.0 network.
PC>ping 10.0.0.1
Pinging 10.0.0.1 with 32 bytes of data:
Reply from 10.0.0.1: bytes=32 time=157ms TTL=255
Reply from 10.0.0.1: bytes=32 time=16ms TTL=255
Reply from 10.0.0.1: bytes=32 time=29ms TTL=255
Reply from 10.0.0.1: bytes=32 time=31ms TTL=255
Ping statistics for 10.0.0.1:
Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),
Approximate round trip times in milli-seconds:
Minimum = 16ms, Maximum = 157ms, Average = 58ms
Step 3:Now ping host 40.0.0.10,we will get
PC>ping 40.0.0.10
Pinging 40.0.0.10 with 32 bytes of data:
Reply from 10.0.0.1: Destination host unreachable.
Reply from 10.0.0.1: Destination host unreachable.
Reply from 10.0.0.1: Destination host unreachable.
Reply from 10.0.0.1: Destination host unreachable.
Ping statistics for 40.0.0.10:
Packets: Sent = 4, Received = 0, Lost = 4 (100% loss),
Step 4:Add static route to Router R1 for the network 40.0.0.0
R1(config)#ip route 40.0.0.0 255.0.0.0 20.0.0.2
Now,Packets that came to Router R1 for the network 40.0.0.0 will be forwarded to 20.0.0.2
Check Routing table of R1 by giving command,
We get reply from 20.0.0.1 because router R1 knows directly connected network.
Step 6:Now ping ip address 20.0.0.2
PC>ping 20.0.0.2
Pinging 20.0.0.2 with 32 bytes of data:
Request timed out.
Request timed out.
Request timed out.
Request timed out.
Ping statistics for 20.0.0.2:
Packets: Sent = 4, Received = 0, Lost = 4 (100% loss),
Destination Host Unreachable Ping Error Message
During my network engineer career, one of the common errors I received while troubleshooting connectivity issues is Destination Host Unreachable.
This error was the cause of my Internet connectivity problems most times.
The same can be true for you too. When you troubleshoot your connectivity problems, the chances of getting this ping reply are very high.
If you learn how to resolve this error by yourself, you can fix most of your Internet connectivity problems yourself. In this tutorial, I will explain everything about this error.
By the first part, you will learn the meaning of this ping reply.
The second part of this article explains the reasons to get the ping reply Destination Host Unreachable.
You will learn how to fix the Destination Host Unreachable ping error in the last part.
What does Destination Host Unreachable Reply Mean?
Before proceeding to the core of this tutorial, let me explain the meaning of this ping reply.
Now you understand the meaning of this ping reply. However, to learn more about this error, you should ask yourself two questions.
Let me answer the questions one by one. But before I explain the first question, you must learn how the ping operation works.
When you ping an address, this is how it works.
Can you tell me the potential sources for a Destination Host Unreachable reply from this ping workflow algorithm?
You can get this reply from two possible sources.
How do you know whether the reply comes from your default gateway or remote gateway?
If you see the following format, check the IP address. Most of the time, X.X.X.X must be a remote gateway address. Which shows the error message you received is from the remote gateway.
If you don’t see an IP address in the error reply, your default gateway sends it.
Both error formats have different reasons. I will explain the reasons to get either format in the next part.
Reasons to Get the ICMP Error Destination Host Unreachable
Any one of the reasons listed below can get you to the ICMP Echo message Destination Host Unreachable.
One of the frequent questions I received from our readers is whether this error is related to the Operating System like Windows error and Linux error?
Analyzing the ICMP Echo Destination Host Unreachable
Let me explain why I received this ICMP Echo by analyzing a live example.
Here I send ping packets to the global DNS address 4.2.2.2 to troubleshoot the connectivity problem. The screenshot below shows the reply I received.
Which format is this? It is the second format of the Destination Host Unreachable error. Let me explain how to resolve this error.
How to Fix Ping Error Destination Host Unreachable?
If you do not want to go into the complexity of this ICMP Echo, you can follow the instructions below to resolve the Destination Host Unreachable Ping error message.
Aggressive firewall settings can cause the destination host unreachable error.
To check whether the firewall is the reason for this issue, disable it on your computer.
Try to access the Internet after disabling the firewall.
Sometimes devices fell into the IP version conflicts. Different operating systems have different IP version priorities.
Windows 10 prefer IPv6 to IPv4. The same is true for the major Linux variants like Ubuntu, Fedora, Debian, etc.
However, sometimes devices fail to work properly with IPv6.
Rarely it results in ICMP error messages. We can check it by disabling the IPv6 on your device.
Let us check how to disable the IP Version 6 on a Windows 10 computer and test the issue.
Once you reboot your computer, check for the connection.
