"Full transit to everybody" was a good idea to get a pretty tightly
meshed IPv6 network into place, which is *good* because it means that
you have (typically) only few AS hops to traverse - and thus fewer
networks in between that can mess up your routing.
Won't help against Ghosts, of course, but there is nothing besides
establishment of a clear upstream/downstream structure and strong
filtering on the downstream BGP sessions to fix *that*.
Total number of prefixes smaller than registry allocations: 45583 (46871)
