New IANA IPv4 DE-allocations and bogon updates

[Rob Thomas <robt at cymru.com>]

[ Apologies to those who have received this post in other fora. ]

The numerous Team Cymru bogon projects have been updated to reflect the
following IANA DE-allocations on April 05, 2003:

173/8   Apr 03   IANA - Reserved
174/8   Apr 03   IANA - Reserved
175/8   Apr 03   IANA - Reserved
176/8   Apr 03   IANA - Reserved
177/8   Apr 03   IANA - Reserved
178/8   Apr 03   IANA - Reserved
179/8   Apr 03   IANA - Reserved
180/8   Apr 03   IANA - Reserved
181/8   Apr 03   IANA - Reserved
182/8   Apr 03   IANA - Reserved
183/8   Apr 03   IANA - Reserved
184/8   Apr 03   IANA - Reserved
185/8   Apr 03   IANA - Reserved
186/8   Apr 03   IANA - Reserved
187/8   Apr 03   IANA - Reserved
189/8   Apr 03   IANA - Reserved
190/8   Apr 03   IANA - Reserved


Note well: These are IP DE-allocations which increases the number of
Bogon networks!  Also note that 188/8 is NOT part of the list above.

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 the FIRST community, as
well as on lists such as NANOG, isp-routing, isp-security, isp-bgp,
cisco-nsp, and bogon-announce.  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 blindly apply any filters or blocks to your network
without carefully considering the ramifications of doing so.
