Subject [jira] [Commented] (CLOUDSTACK-1232) Ipv6 - Guest Vms are not able to get Ipaddress when executing dhclient command when using "/96" network.

Sheng Yang commented on CLOUDSTACK-1232:
----------------------------------------

dnsmasq doesn't support it. We would only support cidr=64.

> Steps to reproduce the problem:
> Create a IPV6 network using “/96” CIDR.
> Deploy a Vm in this network.
> Router assigns an Ipaddress to this VM.
> root@r-51-VM:~# cat  /etc/dhcphosts.txt
> id:00:03:00:01:06:ce:88:00:00:3c,[fc00:3:1380::9fe5:5d25],vm-1380-1,infinite
> But  guest Vms are not able to get the ipaddress.
> I see the following in the router logs when , dhclient request is made from the guest.
