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

Hi, all.

The numerous Team Cymru bogon projects have been updated as of 17 JUN 2005 to
reflect the following IANA allocation made on 17 JUN 2005:

  074/8   Jun 05   ARIN                        (whois.arin.net)
  075/8   Jun 05   ARIN                        (whois.arin.net)
  076/8   Jun 05   ARIN                        (whois.arin.net)

  189/8   Jun 05   LACNIC                      (whois.lacnic.net)
  190/8   Jun 05   LACNIC                      (whois.lacnic.net)

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 through you.

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