IPv4 Allocation stats

Wed Jun 18 19:02:36 UTC 2003

We're not ARIN members so I can't post to arin-discuss - thought someone
here might be able to help me out....

Can anyone explain to me why the ARIN IPv4 Issued statistics, e.g.
http://www.arin.net/statistics/index.html#ipv4issued2003, do not seem to
match up with the stats available from
ftp://ftp.arin.net/pub/stats/arin/arin.20030601?

For example, if you add all the allocations and assignments listed in
arin.20030601 for April 2003 you get 819,456. Dividing by 256 to get /24
equivalents gives 3,201. But
http://www.arin.net/statistics/index.html#ipv4issued2003 states 7,056 /24
equivalents were issued in April 2003.

I'm sure there's a simple explanation. So what is it? Maybe I can't do
arithmetic...
