I can't comment on the validaty of the tests performed, but I'd like to
point out one thing: I like that the NLNOG RING is very diverse,
especially in terms of the node's IPv6 connectivity.
Some hosts are behind exotic 6to4 NATted tunnels, others behind regular
tunnels, some inadvertently block useful ICMPv6 messages, some networks
are just broken.
For NLNOG RING applications we mandate that there is 1 globally unique
IPv6 address on the host, we do not specify how this should be
accomplished. This leads to some variety, not all of those
implementations I would describe as "well behaved".
