So if we go ahead with the present idea there will be a limit on the number of subnets. I also came to know alternative method, we can add multiple ips to the same nic of a VM.

Shrinking an ip range is possible as long as none of the ips which are being removed due to shrinkage are in use.

The upgrade will not modify the existing ip ranges. we can just add new ip ranges after the upgrade. > > Thanks, > Sanjeev > > -----Original Message----- > From: Bharat Kumar [mailto:bharat.ku...@citrix.com] > Sent: Tuesday, January 08, 2013 5:27 PM > To: cloudstack-us...@incubator.apache.org; cloudstack-dev@incubator.apache.org > Subject: [Discuss] Support for multiple ip ranges. > > Hi all, > > Currently in cloudstack we can add multiple public ip ranges. we want to > provide similar flexibility for management and guest ip ranges. > > Motivation: There may be cases where some part of the subnet is allocated for > some other purpose and the admin wants to use the rest of the ip range or > admin may want to add more ip address once the old ones are exhausted.
