Hello everyone, Could anyone explain me the case as follows. For example, OS (Win10) its ethernet network has IP-address say, 100.1.1.100.

Two questions:

  • I'm curious why does the OS get a response while pinging its own address 100.1.1.100.
  • Why another OS also Win 10 with having set, say, 192.169.1.99 doesn't get response while pinging its address. Is there any special settings for that?

thanks!

    Hi,

    Thank you for posting in Q&A! In regards to your issue, here're my suggestions:

    1.Pinging itself successfully is because of TCP/IP is up and running by the computer.

    2.Those fail to ping itself may because of the TCP/IP doesn't work successfully.
    Can you ping 127.0.0.1 successfully on these PCs?

    You can run the following command in PC with problems:
    netsh winsock reset
    netsh int ip reset
    ipconfig /flushdns

    And then reinstall your NICs Driver or update it to the latest version.
