There are 4,035 routes in the global IPv6 routing table. This is what one provider passed on to me for routes (/48 or larger prefixes), extracted from public route-view servers. AT&T AS7018: 2,851 (70.7%) Cogent AS174: 2,864 (71.0%) GLBX AS3549: 3,706 (91.8%) Hurricane Electric AS6939: 3,790 (93.9%) Qwest AS209: 3,918 (97.1%) TINET (formerly Tiscali) AS3257: 3,825 (94.8%) Verizon AS701: 3,938 (97.6%)
Sprint (AS1239) is sending 3,779 routes.
XO Communications (AS2828) is sending 3973 prefixes.
I had a quick look at the diff between routes given to me by AS174 and 6453 and other v6 peers and here is what I found based on missing /32s. (I excluded /48s for now) There are some 490 /32s missing from Cogent from my network in Toronto, Canada. The majority are paths via just 6939. Of those that are not just 6939, I see them via the following AS paths. 11647 6453 293 11647 6453 701 668 11647 6453 30071 13645 11647 13030 15716 11647 6453 5511 11647 6453 6830 11647 6453 25137 11647 6453 30071 2549 11647 6453 30071 10318 11647 6453 6762 7303 11647 6453 30071 11647 6453 6762 8280 11647 6453 13030 11647 13030 11647 6453 701 11647 6453 6762 11647 6453 5511 8346 11647 6453 30071 11647 6453 13030 8271 11647 13030 8271 11647 6453 13030 33845 11647 6453 701 18061 9555 11647 6453 6762 7642 11647 6453 30071 6536 11647 6453 701 18750 11647 6453 30071 19151 11647 6453 701 26773 11647 6453 30071 10326 11647 6453 30071 19151 16842 11647 6453 30071 19151 31877 11647 6453 30071 19151 22911 11647 6453 30071 13911 11647 6453 30071 7786 11647 6453 30071 13911 14595 11647 6453 6762 7303 4270 11647 6453 6762 7303 4270 27770 11647 6453 6762 7303 4270 5692 11647 6453 13030 48218 11647 13030 48218 11647 6453 13030 20634 11647 13030 20634 11647 6453 701 12702 24807 11647 6453 6830 11647 6453 5511 8697 11647 6453 6762 31463 11647 13030 9191 11647 6453 13030 25164 11647 13030 25164 11647 6453 13030 16242 11647 13030 16242 11647 6453 13030 28717 11647 6453 13030 25563 11647 13030 25563 11647 6453 5511 3215 11647 6453 5511 3215 11647 6453 5511 3215 11647 6453 5511 12493 11647 6453 13030 44573 11647 6453 13030 35366 11647 6453 13030 29430 11647 13030 29430 11647 6453 13030 21232 11647 13030 21232 11647 6453 13030 47617 11647 13030 47617 11647 6453 6830 20825 11647 6453 6762 8953 11647 6453 13030 15216 11647 13030 15216 11647 6453 13030 11647 13030 e.g. 2607:f078::/32 11647 6453 701 18750 11647 6939 18750 and 2a01:c910::/32 11647 6453 5511 3215 11647 6939 5511 3215
