Cuckoo IPv6

My firewall has just popped up saying that IPv6 is available on my Cuckoo connection (former Swish Fibre now OneStream). Does anyone have any information on settings? Is it SLAAC or DHCPv6 for example and any information on prefixes?

I have the same setup. It seems to be a beta, not a supported product, and works on and off. It's working for me at present, but twice before it has worked for a month or so then stopped, and I have to disable IPv6 at the router as it causes problems.

My router gets a /64 WAN address via DHCPv6. It also gets a delegated prefix from a different address range, don't know what size because my simple router doesn't expose that, but others have said it's a /56. The router extracts a /64 prefix from it and circulates that round the LAN in RAs. The prefix has a stupidly short lease time of 300sec. Devices use SLAAC or similar to make GUAs from the prefix.

Spoke too soon. Something broke in the APFN V6 stack again yesterday. My V6 BQM stopped working about 11am on 12/6, and has been solid red ever since. Didn't notice till I checked it this morning, because I can still access websites over V6, and my (Pihole, Unbound) DNS is working. But they seem to be blocking pings, and possibly other incoming too.

test-ipv6.com tests are failing. They just come back "bad", which is weird because I can see from the pihole logs that the DNS queries are being returned correctly. But test-ipv6 seems to have issues of its own at present - (at least) one of the mirrors is returning an out-of-date certificate, which causes FF to throw a wobbly, so maybe that's confusing things.
