Now that IP Scanner 1.4 and Port Scanner 1.2 have been available for awhile (they are great of course), I had the following suggestion.
It would be nice if both tools support subnet/maskbits notation. Many of our subnets use an odd number of mask bits which makes entering all the appropriate class C addresses cumbersome. It would be nice to enter 10.20.224.0/22 for example.
It would be very beneficial for IP Scanner to support scripting like Scanner now does - to be able to pass a command file to IP Scanner that tells it to find all the alive computers on a subnet/supernet and to retrieve the NetBios name information from them and write that information to a file. Or to feed IP Scanner a list of MACs and have it wake them.
