Missing routes

In IPv4 land, you could probably get by with a single feed and see the entire internet.  Of course you would not have any redundancy, but apart from the odd spat and peering fight, you could get to everything.  In V6, not so much.  Of the 3 transit peers I have, the numbers range quite a bit.  AS174 is missing about 20% of what AS6939 and AS6453 has. There is idle gossip on http://nanog.org as to the reasons… but there are still some 500 /32s (ignoring more specific /48s which might be reachable through the /32)

BTW, there is a cool tool at
