Yes, I have several LES vps and generally connect to them by v6. The shared ipv4 addresses have a habit of getting ddos'd.
I mostly don't feel like I need v4 for my own servers except for one running a small web site. The rest are personal and backend services of various sorts and v6 would be fine for those. Scaleway.com has a problem right now because they're short of v4 addresses so it's hard to spin up new servers. v6 would mostly solve that but they don't have it yet.

These are the hosts that I know support IPv6 or there lack of.
Feel free to PM/create issues and I'll add hosts that do or don't have them.
