Looks like AS13722 (Default Route, Inc), is advertising both 2607:ff08:cafe::/48 and 2607:ff08::/32.

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%)
TATA (AS6453) out of Toronto, Canada 3,747.
For my v4 transit, I only see 0.3% difference from my largest and smallest view. Where as with ipv6, the difference is almost 25%. For /48 and shorter, I see 757 paths missing from AS174 that I see on my other 2 v6 transit providers.
While looking at whats missing, I found this interesting /48. +2607:fed0::/32 +2607:fed8::/32 +2607:ff08:cafe::/48 +2607:ff20::/32 The 2607:ff08::/32 is visible on Cogent. But I guess they are not serving coffee there, only on TATA and HE. ---Mike
