BT accounts and IPv6

[ravenstar68]

Hi

I've moved up to my parents house to help look after them, and was looking at the IPv6 configuration, is I want to set up OpenVPN tunnel IPv6 over IPv4

I just wanted to clarify some information.

Is the IPv6 allocated as a /56, from which the hub picks the /64 to use?

If yes - is the /56 linked to the account? or the hub?

Thanks in advance.

Neither, for some bizarre reason its dynamic like your IPv4 address

Thanks in advance.

Not sure why you are asking if you are tunneling IPv6 over IPv4

You say it's dynamic, yet we've had the same /64 and consequently the same /56 for well over a year.  The IPv4 address changes at least every other week.

The reason I asked is because I want to set up the tunnel so that a device connected to the VPN from a remote location picks up an IPv6 address from the OpenVPN server.  But from what I was reading, the server needs to allocate a separate /64

Well it is in theory, maybe not in practice.

So are you running the OpenVPN server at your end?

I am in the process of setting it up at the moment.

The hub is using a /64 in the format

2a00:xxxx:xxxx:eb00:xxxx:xxxx:xxxx:xxxx

So I'm assuming the /56 would be 2a00:xxxx:xxxx:eb::

I assume so.
