So, people have tested, and confirm that 1) this ISP advertises link-local address via RA 2) it works with all DNS clients, but the RIPE Atlas probes. Any idea?

I just tried a bare link local address with dig on FreeBSD and it failed. For some reason my attempts on a few linux VMs failed for completely different reasons. The problem is that for a link local address you need a scope. The Atlas measurement code doesn't know how to add one and the addresses in /etc/resolv.conf don't have one. I sort of knew that this was going to be a problem, but link local for the resolvers seems to be quite rare. I'll make a note to see if I can make it work somehow. Philip
