Hi. Patricio,

I thought request is reasonable, so I tried to find my time to
improve our report script. Today, I did it. New report will be
delivered later today. To do it, the script had to know which AS
is a backbone (pTLA). The information is retrieved from 6bone db
but it may be inaccurate or incomplete and there may be a
delay. (Since our report is not intended to blame someone, so
please allow this inaccuracy.)
The right most pTLA's AS (or the left most AS if there is no pTLA
AS) appeared in the path of a poorly aggregated prefix will be
listed to be a candidate who allows this first. If the pTLA
allows prefixes within its pTLA, the entry will be listed with
"*". (Note that even if the pTLA fixes its filter, the same
route may be appeared through another pTLA in the next report.)
I also modified a part of the report which lists reserved AS
numbers used in 6bone. This part now lists unknown AS numbers
that are not registered in 6bone db. (This will result in listing
reserved AS numbers, too.)
The same modification was applied to unknown prefixes. It now
lists prefixes not registered in 6bone db.
I hope this helps 6bone hardening.
