Dynamic DNS update - IPv4 & IPv6 at INWX

[Madtrick]

Hello,
the update URL of my DNS provider INWX is:
Update URL:
https://dyndns.inwx.com/nic/update?myip=<ipaddr>&myipv6=<ip6addr>

I have entered this in the pfsense. Of course the string <ipaddr> was exchanged to
%IP%, so the update URL now looks like this:

https://dyndns.inwx.com/nic/update?myip=%IP%&myipv6=<ip6addr>

This works very well for IPv4.

But what I can't find via the community and the manual is how the string has to look like for IPv6. So for <ip6addr> in the update URL.

Can you guys help me?

The IP variable is the same, but you have to set up a special IPv6 update client so that pfSense takes the IPv6 interface address.
