uh, as these data appear to be the statistics of an attempt to walk the
dns in-addr.arpa tree what confidence is there that this fairly represents
address space assignment/allocation?

e.g. there are 153 /16 announcements in 133.0.0.0 and the table at
http://www.isi.edu/~bmanning/in-addr-data.html shows one in-addr.arpa
allocation entries.

e.g. there are 166 announcements (of 175 /16 equivalents of space) in
147.0.0.0 and the table at http://www.isi.edu/~bmanning/in-addr-data.html
shows 193 in-addr.arpa entries.

so how can the data at www.isi.edu/~bmanning/in-addr-audit.html be
interpreted to give a useful representation of how much space is
assignmed/allocated?
