Interesting. I believe I had the "alias" there at some point, but then
thought it was weird to have the alias on the first IPv6 address and
removed it - doesn't seem to make any difference.

That output looks identical to what I have (except that the IPv6
addresses are different).

At this point I would actually check what you get on the network, i.e.
"tcpdump -npi vioif0 icmp6" - do you see the expected neighbor
solicitations and ping request/replies? (it sounds a bit like the IPv6
network you got assigned has also been assigned to another VPS)
