Are there any VPNs that support dedicated IPv6 addresses?

By dedicated do you mean static? Addresses not shared?

I think the problem is you (and others) using the term “vpn” to cover various different needs.

There’s:

• actual privacy from network observers, which is about only Mullvad
• exploiting non-technical podcast listeners, which is just about every other product labelled “vpn”
• providing better connectivity, which is Tunnelbroker or a GRE/vxlan provider
• joining the DFZ via a crap isp, which is bgptunnel and various more expensive ones

You want 3 or 4, which is fine. Making item 1 provide a subnet doesn’t help 1 do its job any better and definitely will harm unskilled users.
