IANA IPv4 allocations and bogon update: 71/8, 72/8

Hash: SHA1

Hi, team.

[ Apologies to those of you who receive this note in multiple forums.

The numerous Team Cymru bogon projects have been updated as of 02 AUG
2004 to reflect the following IANA allocation made on 02 AUG 2004:

   71/8 Aug 04 ARIN
   72/8 Aug 04 ARIN

IANA allocations change over time, so please check regularly to
you have the latest filters if you are not using the bogon BGP
We do announce updates to the bogon projects to sundry lists, such as
the bogon-announce list. We can not stress this point strongly
enough - these allocations change. If you do not adjust your filters,
you will be unable to access perhaps large portions of the Internet.
Worse yet, you may end up blocking access for people who transit
through you.

Please do not apply any filters or blocks to your network without
carefully considering the ramifications of doing so.

can be found here:
