IPv6 inter VM traffic on public ips
When using public IPv6 addresses, from what I understand there are no transfer costs. Does local ipv6 traffic still end up going over the public network though? If you are connecting to a server in the same Data Center, on its public IPv6 address, will the traffic all be internal to linode's network? Or if I want my traffic to be local do I need to get a private IP for both of the servers?

Does [local ipv6] traffic still end up going over the public network though?
No.
If you are connecting to a server in the same Data Center, on its public IPv6 address, will the traffic all be internal to linode's network?
Yes. The traffic would stay within our LAN.
Or if I want my traffic to be local do I need to get a private IP for both of the servers?
Nope, v6 can do this job just fine, thanks to its huge address space and math and our addressing/netmasking scheme.
Hope that helps!

Thanks that's very helpful.
Another thing, is it possible to communicate over the link local IP? From what I understand it's not usually routed in IPv6, so you can't communicate with other servers in the same data center over the link local IP. Is that correct words possible?
