I read that pinging loopback will work if we have TCP/IP suite installed on our computers and don't necessarily have a NIC. So, do we need NIC to ping loopback ip( ?




Quoted from this answer http://forums.pcper.com/showthread.php?336976-Can-you-ping-127-0-0-1-if-your-NIC-card-is-burned-out

Actually is just the loopback address for TCP/IP protocol stack. It let's you know you have the protocol installed and windows is recognizing it. Has nothing directly to do with a NIC, as you can still do this test with a generic modem in a system without LAN network hardware or access.

Loopback address is a special IP number ( that is designated for the software loopback interface of a machine. The loopback interface has no hardware associated with it, and it is not physically connected to a network. The loopback interface allows IT professionals to test IP software without worrying about broken or corrupted drivers or hardware.

So that means you do not need a NIC to be able to ping your loopback addresses.

  • So that's actually a "No", isn't it? Or at least "Yes, but not necessarily a physical one..." – user1686 Feb 22 '17 at 8:50
  • @grawity Yes you are right. I forgot to change the Yes to a No. Loopback address is not associated with both physical or virtual nics. – RamonRobben Feb 22 '17 at 9:02
