That number is still too high since some people are advertising their /25 to
/32 prefixes to the route-views box..

      I was going off my data analysis of
route-views data.

wc -l oix.home_as.out
  135949 oix.home_as.out

      this file has prefix:home_asn

      (where home_asn is the last asn in the as_path.  prefixes
with inconsistent home_as will appear twice.  this may be 
cause of some
of your confusion.  eliminating those brings it to 120131 prefixes)

"about 135k prefixes last i checked." is not what we see 
here from any of 
our upstreams.
