Hello Nodelist,

Indeed, not a good solution.

Saying goodbye to ddns.net is what I would have done. IPv6 is not something that was invented yesterday. Any DNS provider that has not fixed IPv6 issues yet, deserves to go belly up.

 NC> and just put the IPv6 in the nodelist.

Ah, you mean just do away with DNS alltogether and just list the literal IPv6 address. If is is a static address that woukd indeed be a workable solution.

From what I understand, this IS the fix. Before that it was not possible to have an IPv6 address when you have an IPv4 address. It was either one, but not both. Now it is IPv4 only or IPv4 + IPv6. But not IPv6 only. :(

 NC> Btw: Did you get an explanation for the identical /64 on all the

No, I did not bring that up yet...

Cheers, Michiel
