Filtering Previously Unallocated Addresses
Hi NZNOG Community, I realize that Andy Linton sent this to the list a couple of weeks ago. However please note that 36/8 and 42/8 have now been added as newly allocated address blocks managed, by APNIC. Kind regards, Elly APNIC _______________________________________________________________________ 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. http://www.ripe.net/projects/ris/index.html * 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. http://whatismyipaddress.com/blacklist-check * Use a looking glass service as part of the diagnostic tool, set to detect network filters. http://www.ris.ripe.net/cgi-bin/lg/index.cgi Ongoing testing --------------- 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.
