@vmh use baserange/112 instead of baserange/64 for your config.

@Michael – you are actually correct. Once I sorted out what was going on: I was looking at the wrong thing – that was actually a loopback IP address. I was assigned a block of IP addresses (from ::f000-f00f).

These are verifiable. The problem is that in any of the articles I have read on configuring IPv6 VPN’s, it requires (or strongly recommends) a /64 block. It appears that Digital Ocean is assigning me a /112 block of which I need one address for the server itself.

This won’t work from what I understand. My dilemma is that I cannot find anything that addresses this on Digital Ocean. It seems extreme to open a ticket for this – I am a little astonished that no one seems to have the same problem … almost like I am missing something very obvious.

@vmh: fe80 is a localhost IPv6 address. Are you really sure your ISP assigned it? Google ipv6 test and do an ipv6 test to see if you actually have ipv6 and post the result.

I am still struggling with IPv6 addresses. The author mentioned the "BASE RANGE" above in the configuration that the ISP assigns. For myself, I have been assigned an IP address like this: "fe80::[group]:[group]:[group]". I am stuck trying to understand out of this mess what is the "base range" that I should use for my OpenVPN server configuration. Unfortunately, even a Google search of "IPv6 Base Range" doesn't give much useful information. Any help would be appreciated.
