And for almost all of it, there is Team Cymru:

show ip route 172.0.0.0   
Routing entry for 172.0.0.0/9, supernet
  Known via "bgp", distance 20, metric 0
  Tag 65332, type external
  Last update from 192.0.2.1 3w1d ago
  Routing Descriptor Blocks:
  * 192.0.2.1, from 38.229.66.20, 3w1d ago
      Route metric is 0, traffic share count is 1
      AS Hops 1
      Route tag 65332
      MPLS label: none

(192.0.2.1 is null routed statically)

A very handy service!
