I don't think that's the issue. The message just means your browser can't find a DNS A record (or IPv4 address) for that address. It could be a typo, it could be that the site has been taken offline, it could be an issue with the DNS. It is extremely unlikely that the site can be reached via IPv6 (that is a DNS AAAA record, or IPv6 address), for the simple reason that a lot of people can't use IPv6. Loops of Zen seems to be set up to make a point. You can check this from a terminal: > dig +short www.loopsofzen.co.uk Shows the A record(s) (IPv4 address) of the domain, if any, while > dig +short aaaa www.loopsofzen.co.uk Shows the AAAA record(s) (IPv6 address). If you want to change ISPs anyway, looking for one that supports IPv6 is a good idea. If, however, you're happy with your current ISP, I would just ask them if they intend to support IPv6 - and perhaps use Loops of Zen as an argument. Of course, you may want to be a good netizen and decide you only want to give money to ISPs that support IPv6. That would probably be a good thing. However, don't expect you can suddenly see things you couldn't see before - Loops of Zen excepted.
