> @wido thanks ! > > some more questions > (1) it looks startipv6 and endipv6 can be removed from cloudstack. am I right ? Yes, indeed. > (2) I notice ipv6 is disabled in virtual routers. do you have another dhcp server for ipv6 ? No. As we send out the DNS servers through the IPv6 Router Advertisements from the routers. DHCPv6 is not being used in our environment. In addition for DHCPv6 you do not need a global IPv6 address. This can work over just IPv6 Link-Local. > (3) in commit [f967944](https://github.com/apache/cloudstack/commit/f967944d900847c9a2020f9aa81f5db09ee78a1c), it prevents a EUI-64 to be used by other vms as secondary IP. is it possible that two vms use same secondary ip ? > I am not sure. I think that is handled by different code. > Thank you. > -Wei > > > > @wido @GabrielBrascher > > > I have some questions regarding the ipv6 allocation. > > > (1) startipv6 and endipv6 are not used any more. right ? is it expected behavior ? > > > > > > Yes. That is expected as DHCPv6 is not being used for address distribution. > > Please note that this never worked.

We could still use DHCPv6 for distribution domain name and DNS servers. Although the IPv6 Router Advertisements support this as well. > > > (3) is there check for duplicated ipv6 ipaddress (secondary ips) ? > > > > > > Yes, that check is available for secondary IPs.
