Nope, we didn't forget or ignore it. The numerous Team Cymru
bogon projects have been updated as of 15 JAN 2004 to reflect the
following IANA allocation made on 15 JAN 2004:
70/8 Jan 04 ARIN
IANA allocations change over time, so please check regularly to ensure
you have the latest filters if you are not using the bogon BGP feed(s).
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
Please do not blindly apply any filters or blocks to your network
without carefully considering the ramifications of doing so.
As a point of reference, the Team Cymru master Bogon Reference Page can
be found here:
