Please note you are allowed max 20 IPv6 per VPS as too many IP can cause ARP cache issues, hence this is the limit set per VPS
This is exactly why you should provide veth network interface and routed IPv6 subnet.
There would be two entries in the router/switch, regardless of how many IPv6 addresses are in use.

We cannot use veth because as far as i know Virtualizor Control Panel has no support for it, we will probably need to manually setup VPS for it.
If we use routed IP then just in case if the VPS Node IP gets nulled for any reason then even all the VPS IP will go down, we have a common pool of IP for KVM as well as OVZ VPS Nodes, so if we set routed for IP pool that's being used for OVZ it will even set as routed for KVM VPS nodes which we don't want to do.
Moreover these are low end VPS and we hardly get such special requests, for 99% of the users just 1 IPv6 is enough, and if we don't impose these limits we have seen users who try to add 100ds of IPV6 IP and then later complain why is their VPS so slow as most of the resources are being taken via the network stack and also causes ARP issues.
Sorry but we are trying to give LES deals but also trying to keep them sustainable, we cannot change our whole setup for it.
I've not tried routed IP recently, but from what i remember it was causing some issue and right now no intention to change any configuration with our existing setup.
I agree it is a great panel from a users perspective. Can't say if it is the same from the providers perspective or not. Personally I do prefer it when a potential KVM VM I am looking to purchase has a /64 of IPv6. OpenVZ 7 has limitations and one of them seems to be the way they handle IPv6 by default. Yes you can use veth network interfaces but it does add an additional layer of complexity to an already very low end product IMO.
@yoursunny said: The entire subnet is directly usable in the VPS.
Indeed, but the problem is if and when you need to set rDNS for those IPs
I'm sure the provider can help via a ticket but it would make sense if they would just allow users to add and remove custom IPs via the panel - similar to what was possible on SVM.
For maximum flexibility, the panel should delegate the reverse zone to a nameserver chosen by the user.
User can then have as many rDNS records as they want.
@yoursunny said: For maximum flexibility, the panel should delegate the reverse zone to a nameserver chosen by the user.
Yes, that would be a lot better
Some providers can and do support this, but I believe only if it's for a /48 block, or bigger.
TunnelBroker.net can delegate /64 prefix.
Thus, there's no technical reason to require /48 subnet for rDNS delegation.
I was referring to providers that are providing native IPv6, that they would normally support delegating NS auth for the subnet if it was at least a /48.

You can create NS record(s) for any prefix like /64.

I think so.
Both @skhron and @crunchbits delivered routed IPv6 in VirtFusion.
Nice! We also use vf for kvm services. Would any of you be kind to share how to achieve this
I think this is on a per Hypervisor basis with a routed subnet for each HV, but that will make it impossible to migrate between nodes. Also won't work for a vlan setup.

As the hypervisor can run a hook after booting a virtual machine, the hook script can either:
SSH into the hardware router(s) and insert/replace a static route for the VM prefix.
Make an intra-domain routing announcement for the VM prefix from the routing daemon on the hypervisor node. This routing announcement would be received by hardware routers and other hypervisor nodes.

In our case the routes are added to the Linux routing table and they are further propagated by iBGP, no need for quirks with SSH

LXC or OpenVZ with veth network interface would be acceptable.
Accepting submissions for IPv6 less than /64 Hall of Incompetence.

I could not find a way to automate routed IPv6 setup using any panel.

Just a comment about VF, from a customer's experience and POV, I personally like it.
Things I would like it to have are:
Caught it this time!

Fixed. Thank you for your support.

Just add millions of addresses in Netplan.

I never bothered with rDNS in VPS.
I only used rDNS once at a hackathon, with tunneled subnet.

It should not, however I didn't test it yet.
I don't see any reason why vlan will interfere (our hypervisor uses vlans and has very custom network setup)
