I realised that if I use any of those IP's to another machine (it happened by mistake.), I lose internet access in my Linux box, and the domain is unreachable. Kinda normal(?), but it could be dangerous if someone hack into one of the Win boxes and start changing IP's.that
If someone is able to change the IP-adress on a Windows box, he might be able to do some other things, too.
won't be problem if there is a way to block giving the same IP to 2 machines (just like the Win boxes do when you try to give them an IP already used in the same netmask). Otherwise, it can be considered as an important security hole, am I wrong?
To change IP adresses is neither a bug nor a security hole, it's a feature :-)
That reminds me that all the exploitable features in Win boxes...
