[ 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. As a point of reference, the master Bogon Reference Page can be found here: http://www.cymru.com/Bogons/index.html A quick summary of the documents and projects that have been updated include the following: HTTP The Bogon List The Text Bogon List, Unaggregated The Text Bogon List, Aggregated Secure BIND Template Secure IOS Template (Cisco) Secure BGP Template (Cisco) Secure JUNOS Template (Juniper) Secure JUNOS BGP Template (Juniper) Ingress Prefix Filter Templates, Loose and Strict (Cisco) Ingress Prefix Filter Template, Loose (Juniper) Ingress Prefix Filter Template, Strict (Juniper) BGP Bogon route-server * RADb fltr-unallocated fltr-martian fltr-bogons DNS Bogon (bogons.cymru.com) zone Monitoring Bogon prefix monitoring * All of the bogon peers have received the appropriate BGP prefix updates.
