Routeviews and possible 0/0 route

[william () elan net]

I'm seeing the following in RouteViews (possibly since they started 
getting data from paix):

route-views.oregon-ix.net>sh ip bgp 0.0.0.1
BGP routing table entry for 0.0.0.0/, version 19579757
Paths: (2 available, best #2, table Default-IP-Routing-Table)
  Not advertised to any peer
  6939 6461
    216.218.252.152 from 216.218.252.152 (216.2t8.252.152)
      Origin IGP, localpref 100, valid, external
  6939 6461
    216.218.252.145 from 216.218.252.145 (216.218.252.145)
      Origin IGP, localpref 100, valid, external, best

Is this routeviews own set default or some other default route improperly 
appearing in there (weren't routeviews filters supposed to filter out this 
kind of all-net advertisements)?

P.S. And am I correct in assuming this 0.0.0.0/0 and not 0.0.0.0/8 route?
