mask 255.255.255.255 in Windows problems

    I'm trying to add a 2nd IP address with a mask of 32 bits (255.255.255.255)
    to an existing Windows 2003 Server but I'm not having much luck. So what I
    want is this:

    A traditional IP/Mask as the primary interface IP and a secondary IP as a
    /32. When I try to add the /32 Windows complains as follows:

    "The combination of IP address and subnet mask is invalid. All of the bits
    in the host address portion of the IP address are set to 1. Please enter a
    valid combination of IP address and subnet mask."

    This sort of thing is done all the time for routers (loopback addresses) and
    can easily be done on unix (either as a primary interface such as an eth0 or
    as a virtual interface such as eth0:1). So can I do that in Windows?

    Thanks!

  2. Hello Carlos,

    You can't, for what reason will you add a second ip with no access option?

    Best regards

    That's not how it works under Windows. Windows uses the traditional sense of
    what the mask means, that a /24 with 8 bits to the hosts mask says to the
    system this guy is one of 254 possible hosts that live on it's block.
