    Thanks for the easy to understand tutorial. I just want to point out a minor correction that got me a bit confused. In the 3rd table, which I copied below, the ip addresses are missing a “1” after the last decimal as “.25” should be “.125”, “.26” should be “.126″…etc.

    Adapter IP Address Type
    eth0 Primary
    eth0:0 Alias 1
    eth0:1 Alias 2
    eth0:2 Alias 3

    This should be the correct table consistent with the ip addresses used in the example by the author:

    Adapter IP Address Type
    eth0 Primary
    eth0:0 Alias 1
    eth0:1 Alias 2
    eth0:2 Alias 3

      Yes, you are correct those IP addresses needs to be like 125, 126 and so on. I have corrected in the article..

  10. Mahesh says:

    Can we add to different subnet if yes then how

    • Vijay Bisalahalli says:

      If you want to create a virtual interface with some subnet, the respective subnet should be physically connected to the machine
