This might do the trick for you 

foreach(NetworkInterface ni in NetworkInterface.GetAllNetworkInterfaces())
{
    foreach (UnicastIPAddressInformation ip in ni.GetIPProperties().UnicastAddresses)
    {
        if(!ip.IsDnsEligible)
        {
            if (ip.Address.AddressFamily == System.Net.Sockets.AddressFamily.InterNetwork)
            {
                // All IP Address in the LAN
            }
        }
    }
}

The Only drawback of this code is that the information returned by instances of UnicastIPAddressInformation is not available for operating systems earlier than Windows XP.

If you already know the hostnames (as your question implies), you can use the Dns.GetHostAddresses method to translate them to IP addresses.
