IANA IPv4 allocations and bogon updates: 186/8 and 187/8
|
|
-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1
Greetings Everyone,
The numerous Team Cymru bogon projects have been updated as of 28 SEP
2007 to reflect the following IANA allocation made in September of 2007:
186/8 Sep 07 LACNIC (whois.lacnic.net)
187/8 Sep 07 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.
As a point of reference, the Team Cymru master Bogon Reference Page
can be found here:
