C'est vrai que c'est un bon avis, ça. Maintenant que quasiment tout
l'espace IPv4 est alloué ou va l'être très bientôt, est-ce vraiment
utile de continuer à filtrer les bogons ?

Filtering Previously Unallocated Addresses
___
APNIC recognizes that as the IANA pool of unallocated IPv4 addresses
nears exhaustion, there may be increasing community concern about the
quality of the new address blocks made available for distribution.
It is important that you ensure your router Access Control Lists (ACLs)
are updated so addresses are not mistakenly filtered through your
routers. It may also be time to consider whether you should stop any
form of BOGON filtering.
This is especially important for newly allocated address blocks:
* 1.0.0.0/8
* 14.0.0.0/8
* 27.0.0.0/8
* 36.0.0.0/8
* 42.0.0.0/8
* 49.0.0.0/8
* 101.0.0.0/8
* 223.0.0.0/8
Keep informed about IANA allocations at:
http://www.iana.org/assignments/ipv4-address-space/ipv4-address-space.xml
For those with recently allocated address space here are several tips
to check whether your IP Addresses are filtered:
* Your own firewall might be blocking the new IP addresses by
default, if you set up your servers to block bogon IP ranges. To
avoid blocking potential new customers, consider whether you
should stop any form of BOGON filtering.
* Run a traceroute to see if the new IP is consistently blocked
along the same network path. It is advisable also, to test
forward and reverse paths. Use of technology like the Routing
Information Service (RIS) is highly recommended to assist in
identifying routing conditions for prefixes under test.

* Do a search on your IP address and contact those organizations
that appear to be blocking you. You may be blocked due to
activity of one of your customers.

* Use a looking glass service as part of the diagnostic tool, set
to detect network filters.

As part of our service commitment to our Members and the wider
community, APNIC is working hard to evaluate the usability of address
space allocated to APNIC before it is distributed.
