Option of specifying custom dhcp range is available while creating a new guest 
network - You can specify custom guest gateway and network during network 
creation that would override the default zone level CIDR. But this is not 
allowed if you choose a network offering that uses external devices (like 
Netscaler for example). The CIDR is generated by CloudStack in that case.

For existing network, I think updateNetwork API does provide an option to 
change cidr. But if you already have running VMs in the network, I am not very 
sure of the behavior in that case.

Subject: DHCP IP range in the isolated network

Hi Folks,



By default the guest CIDR for the advanced zone is 10.1.1.0/24 and the dhcp ip 
range is on the entire subnet.

Does it possible to modify the default dhcp ip range in this isolated network ?



Thanks,

Fabrice
