    Those numbers look really low to me.
    
    Did you query that from only IPv6-enabled RIPE Atlas anchors ?

    Or is there are large number in that pool that don't have any
    IPv6 connectifity ?

Read again: 

    > I just queried all IPv6-enabled root name servers from 51 RIPE Atlas
    > anchors ...

So only the 51 anchors where used, not the flock of probes.
