Hi, team.

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.

As a point of reference, the Team Cymru master Bogon Reference Page can be found here:
