Connectivity testing is currently being done by Team Cymru on the following three /20s (one from each /8). All of these test allocations originate with AS36666.
74.63.0.0/20 75.127.0.0/20 76.191.0.0/20
and how is that testing being done?
look in the routing tables of routeviews/ripe/cymru/renesys peers?
how do we test that we can reach the prefixes?
look in your routing table?
i.e. is there a pingable address in each, as has been discussed here just a few times?
ping is ok, but routing table entry existence seems better. ping can fail for lots of reasons and what we're really testing is routing, not icmp end-to-end, right? if it's useful, i'd be happy to report what percentage of my peers have/don't have routes to these prefixes. todd
