Hi,
from what I see, it's possible to manage / Add IPs in both LXC and KVM guests without any Control of the admin
mean, I can assign 80.179.1.1 to LXC and this host can add
eth0:0 for 80.179.1.2
eth0:1 for 80.179.1.3
eth0:2 for 80.179.1.4
etc...
even I assigned only one interface and one IP (80.179.1.1) for that guest
same for Windows and Linux KVM guests

there is any option to manage and limit the IPs / network for guests only to the IPs that assigned by Proxmox admin?

Regards,
 
Well the IP assignment is not done by proxmox admin but by guest (LXC,KVM) admin. Proxmox doesn't know and can't control what IP is used by the guest admins. In my opinion the only possible way to limit what IP the guest admin can use is to set up firewall rules (by using Proxmox Firewall or directly by iptables/ebtables/arptables) and limit the access only to specific IP.
