Basic networking issue

[Mārtiņš Jakubovičs]

Hello,

I test right now infrastructure with base network setup. I faced issue, 
if I deploy instance, I am able manually add more public IP's. For 
example, I deploy VM, though DHCP I acquire IP, and I can manually add 
alias IP addresses without problems and CloudStack still think that I 
use only one IP. If IP address is acquired and other user boot VM can be 
situation when new VM can't get public IP. Am I doing something wrong or 
is this kind of security "hole" in Basic Networking?

Thanks.
