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

Greetings Everyone,

The numerous Team Cymru bogon projects have been updated as of 05 JAN
2006 to reflect the following IANA allocation made on 05 JAN 2006:

    121/8   Jan 06   APNIC                    (whois.apnic.net)
    122/8   Jan 06   APNIC                    (whois.apnic.net)
    123/8   Jan 06   APNIC                    (whois.apnic.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.
