'With this small application , you can detect the IP's installed on your computer,
'including subnet mask , BroadcastAddr..
'
'I've wrote this because i've a programm that uses the winsock control, but,
'if you have multiple ip's  installed on your pc , you could get by using the Listen
' method the wrong ip ...
'Because Winsock.Localip => detects the default ip installed on your PC ,
' and in most of the cases it could be the LAN (nic) not the WAN (nic)
'So then you have to use the Bind function ,to bind to your right ip..
'but how do you know & find that ip ?
'you can find it now by this appl.. it check's in the api.. IP Table..
