I am currently with Zen Internet. zen.co.uk. After joining them, they say you need to send them an email and IPv6 is then enabled. It worked, I am using IPv6 seamlessly with zen.co.uk. At least https://test-ipv6.com/ says so. Zen are reasonably priced and have responded to any support questions I had in a reasonable amount of time. Even to the point of them telling me that I would get exactly the same speeds on a cheaper tariff which I of course switched to. !!! If Plusnet promised IPv6, and are not delivering it, that is probably breach of contract, and you should be able to exit that contract without penalties and try an ISP that works.

I am trying to set up a replacement firewall, but I discovered a few more problems when one of two boxes running Bind9 locally died a few days ago. It seems that some of the RaspberryPi boxes have changed the name of their ethernet interface again, and could no longer find the IPv6 gateway. -- Chris Bell Website http://chrisbell.org.uk -- GLLUG mailing list GLLUG@mailman.lug.org.uk https://mailman.lug.org.uk/mailman/listinfo/gllug

[GLLUG] IP address problems.
Hello, "Every interface can have multiple IPv6 addresses, while multiple interfaces can respond to a single IPv6 address." Unfortunately I find that boxes generally forget all but the last IPv6 address allocated remotely. I have multiple networks behind a firewall and want to allocate local IPv4 NAT addresses, 2001::/16 global IPv6 addresses, and local fd00::/8 IPv6 addresses, all of which which will survive a re-boot. All regular boxes are running up- to-date Debian 10 Buster with or without KDE, and the RaspberryPi boxes are running the equivalent RaspberryPi version of Debian Buster, although some started as Raspbian while others the more recent Raspbios. My ISP Plusnet has failed to provide IPv6 as promised, and my contract does not expire until next March. I have tried to configure an IPv6 in IPv4 tunnel via Hurricane Electric, but it is not yet working through my firewall. I have also followed the instructions in RFC 4193 to generate local IPv6 addresses, but they have frequently been forgotten after a re-boot. My firewall is running dnsmasq and RADVD, and I have another box running bind9 which should be available locally. I can use "ip address add" for IPv6 addresses, but they have not always survived a re-boot. I have tried entering all IPv4 and IPv6 addresses in /etc/network/interfaces but with inconsistent IPv6 results, although I have had some success using files in /etc/systemd/network/... The RaspberryPi default is to use /etc/dhcpcd.conf to specify either a set of static addresses or a set of static fallback addresses, but the name of the ethernet device has not been consistent. The device name read from "ip address show" has varied over time between "eth0", and "enx" followed by the twelve HEX characters of the MAC address without any ":". The configuration fails every time the device name changes, although I have found that the MAC address does correctly match the hardware following a change of MicroSD. -- Chris Bell Website http://chrisbell.org.uk -- GLLUG mailing list GLLUG@mailman.lug.org.uk https://mailman.lug.org.uk/mailman/listinfo/gllug
