Hi All,

 

We are having a little trouble with a new IPv4 address range recently received from APNIC.  The range is 223.165.16.0/22 (although according to APNIC it affects the entire /8).  Please see the attached email.  It seems that there are some routers which have blocks on this range, which need to be lifted.  Some of the sites we cannot connect to include: airnz.co.nz and dse.co.nz.  We suspect some email is also not getting through.

 

Can anyone suggest how best to get these routing blocks lifted?  My shiny new IP address range is starting to feel distinctly second-hand.

 

Any help you can provide would be warmly welcomed.

 

Thanks Richard

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

    * 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.

    * Use a looking glass service as part of the diagnostic tool, set

      to detect network filters.

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.
