The list seems to be showing relays that announce both the IPv4 and the 
IPv6 anycast prefixes.

I have noticed a number of deployments that announce the (in)famous IPv4 
prefix and then consider their deployment complete. I suspect that there 
is a lack of 2002::/16 announcements and this would be contributing to 
the regular problems with return paths.

Obviously the IPv6 content networks benefit the most from having a relay 
translating back to IPv4.

Anyone have experience with this?
