When I run the command ping I get the following results:

Pinging with 32 bytes of data:
Reply from Destination host unreachable.
Reply from Destination host unreachable.
Reply from Destination host unreachable.
Reply from Destination host unreachable.

Can anyone help me understand why in the world it's telling me that is unreachable when that's not the IP address I typed in? I'm very confused.

Also in case it's relevant, I'm on a workgroup.

  • What command have you typed exactly? – gronostaj Nov 5 '13 at 8:01

    BVernon: it doesn't say "" is unreachable. On the contrary, it is that say that the Destination host (ie, is unreachable. In your case .1.2 is probably your own machine. But it could also be a "hop" along the way to the destination (the last hop that was reached). It could mean that the destination is not answering ping (due to its firewall, for example. do NOT disable the firewall! just allow incoming ICMP) – Olivier Dulac Nov 5 '13 at 11:45
17 should be your ip, not the destination host. If the destination host is unreachable, it can not send you a reply (obviously), so the reply comes from your own machine.

This is because on the same subnet, ping sends an ARP request to get the MAC-Adress corresponding to the IP. if this cant be resolved, you get this message. If you ping a machine on another subnet, you get a time out message, because ping sends an ARP request to get the Gateway of the subnet, which should complete fine. But then the actual pinging times out

  • You can confirm it's your ip by typing ipconfig /all – Vijay Nov 5 '13 at 9:58
  • Ah, I feel like a dummy for not noticing that. The original problem (that it was pinging the wrong ip address for a specific computer name) has fixed itself over night. However, I still find it odd that I can't get on my router ( from this machine even though it doesn't seem to be setup any different than other machines on my network. But at this point that's not slowing me down so I'll save that conundrum for another day. – BVernon Nov 5 '13 at 16:20
1 is some computer along the way, directly connected with your pc, telling you it cannot complete its task.

For instance, supposed your pc is cable-linked to another pc, which should be connected via wifi to a network, but the wifi connection dropped for any reason. Then the pc you are connect to do will send exactly the reply you have received.

Like Hercules' pillars, it is saying, nec plus ultra, i.e. no further than here. It means has a connectivity problem.

  • The last sentence is true, but the first sentence misses the most simple possibility: that, the computer with connectivity problems, is the PC itself. – MSalters Nov 5 '13 at 10:30
  • Nope: when the pc issuing the ping command is the one without connection, there is no "Reply from ..." statement. – MariusMatutiae Nov 5 '13 at 10:39
  • FYI, is the computer where the ping was originating but no it did not have a connectivity problem as I was obviously having no trouble getting on the internet and posting this question from it. – BVernon Nov 5 '13 at 16:24
  • +1 anyway though cause maybe that info will help someone with a similar but different problem down the road. – BVernon Nov 5 '13 at 16:24
  • @MariusMatutiae i explained in my answer why there is a reply in this case – Simiil Nov 6 '13 at 1:59
