What to Know

  • Test the IPv6 connection to determine the default gateway IP, then compare it to the device’s configured gateway via netshell IP settings.
  • Add a gateway: LAN settings > Internet Protocol Version 6 (TCP/IPv6) > Properties. Change Default Gateway to the correct address.
  • To check if the error is resolved, enter a ping test in Command Prompt: C:\Users\Me>ping -6 151.101.194.114.

Receiving a address host unapproachable erroneousness in a Command Prompt network ping test can be frustrating. In this lead, we show you how to fix a finish master of ceremonies unapproachable error on Windows devices, vitamin a well as how to add the correct gateway address for a destination server, and how to check if the error is resolved .

How to Fix a Destination Host Unreachable error

In diagnosing the erroneousness, it ‘s utilitarian to follow the steps to fix an IPv6 error first to see if they resolve your network issues. If the trouble persists, you need to look at your network infrastructure to establish where the write out is.

For this exemplar, we ’ rhenium going to check our Default Gateway settings, then follow the steps to fix them .

  1. To start, we need to check our internet connection via a browser. For this case, we ‘ll check google.com to see if it loads on our device. If it does, we know there ‘s a problem on our local network, quite than a broader connection issue .

  2. following, we ‘re going to test our IPv6 connection to see if that ‘s where the issue lies. To do this, open the Command Prompt and use the following command to ping your master IP address, but type “ ping -6 “ to isolate the IPv6 course .

    C:\Users\Me>ping -6 151.101.194.114
  3. You should get a answer in the Command Prompt, which looks like this :

    Pinging 151.101.194.114 with 64 bytes of data:
    Reply from 151.101.194.1.241: Destination host unreachable.
    Reply from 151.101.194.1.241: Destination host unreachable.
    Reply from 151.101.194.1.241: Destination host unreachable.
    Reply from 151.101.194.1.241: Destination host unreachable.
  4. The above reply comes from IP address 151.101.194.1.241, which seems to relate to the outside gateway handling our request. To check this, run a traceroute using the follow dominate :

    C:\Users\Me>tracert -6 -d 151.101.194.114
  5. You should get a response, and it should resemble the following :

    Tracing route 151.101.194.114 over a maximum of 30 hops:
    1 1 ms 1 ms 1 ms 151.101.194.1.241
    2 151.101.194.1.241 reports: Destination host unreachable.
    Trace complete.
  6. From this, we can make a judgment that 151.101.194.1.241 is configured as the default gateway. To check if this is as it should be, we can look at our IP settings via the netshell. To launch netshell, enter the follow instruction :

    C:\Users\Me>netsh
  7. With netshell exposed, enter this command :

    netshell>interface ipv6
    netshell interface ipv6>showconfig
  8. The reception will show our Local Area Connection details, with a reference course for the Default Gateway. In our example we see the adopt :

    Default Gateway 151.101.194.1.241

    This confirms that 151.101.194.1.241 is presently configured as the nonpayment gateway, but when we look at our actual device ‘s IP address, we see it ‘s slenderly different : 151.101.194.1.244 .

cause of a Destination Host Unreachable error

There are many potential reasons for getting a “ destination horde unapproachable ” error, including things arsenic simple as mistakenly connected cables or an excessively aggressive firewall. As you can see from the details below, we ‘re trying to ping a specific network device IP address, but the response we ‘re getting does n’t provide a lot detail beyond the mistake itself :

C:\Users\Me>ping 151.101.194.114
Pinging 151.101.194.114 with 64 bytes of data:
Reply from 151.101.194.114: Destination host unreachable.
Reply from 151.101.194.114: Destination host unreachable.
Reply from 151.101.194.114: Destination host unreachable.
Reply from 151.101.194.114: Destination host unreachable.

indeed, what ‘s going on here ? In simple terms, we ‘re trying to communicate with a device at the pin down IP address, but the distant gateway is ineffective to direct our ping request to the horde itself, and so it sends an echo message back to say that it ca n’t be found .

How to Add the Correct Gateway Address for a Destination Host

From the information gained above, we can see we need to add the correct gateway address via our Local Area Network ( LAN ) settings. To do this, follow these steps .

  1. Select Settings > Network and Internet > Network Connections .

  2. Right-click the relevant Local Area Network. then, choose Properties .

  3. From the list, choice Internet Protocol Version 6 (TCP/IPv6). Next, choice Properties .

  4. In the Properties check, change the Default Gateway to the chastise address. sol, in this model, we change “ 151.101.194.1.241 ” to “ 151.101.194.1.244. ”

  5. Press OK to save the changes .

How to Check if Destination Host Unreachable Error Is Resolved

  1. To check if the consequence is resolved, go back to the Command Prompt and exit the netshell using the following control :

    netsh interface ipv6>exit
  2. now, we ‘re quick to try our ping test once more, using this command :

    C:\Users\Me>ping -6 151.101.194.114
  3. good as ahead, the ping should come back with a answer showing the new Default Gateway.

    Pinging 151.101.194.114 with 64 bytes of data:

  4. As we can see, our ping test is now working and our connection is running vitamin a expected .
