Jon,
I will lend you the IP list I have so far. IBM is top of the list for
sure
The bogon entry was removed in Aug for 72.0.0.0/8 yet people haven't
revisited to update the filters.
Changes in version 2.5 (02 AUG 2004)
71/8 and 72/8 allocated to ARIN (AUG 2004). Removed from the bogon
lists.
Thanks for all the response people.
