I'd like to display on a webpage a list of computers and what IP address they are at. so maybe display  a list of computers in the subrange of 10.1.1.*

so loop through 255 ip's ping or lookup or however it is you do it and see if that ip address is open or not.

Anyone have some suggestions on how to do this?

hi Jay,

try this code:

// store list of computers
ArrayList computers = new ArrayList();

// get computer list
for(int i = 1; i<256; i++)
{
    try
    {
        IPHostEntry hostentry = Dns.GetHostByAddress(new IPAddress(new byte[]{10,1,1,1}));
        computers.Add(hostentry.HostName);
    }
    catch{};//fail
}

Good Luck,
VINHNL
