APNIC First to Run Out of IPv4 Addresses

Someone had to be first, and it looks like it’s APNIC. Earlier this year all of the regional registries were given a final /8, and APNIC is the first to reach the end game. Have you thought about your IPv6 plans lately?


Dear APNIC community

We are writing to inform you that as of Friday, 15 April 2011, the APNIC
pool reached the Final /8 IPv4 address block, bringing us to Stage Three
of IPv4 exhaustion in the Asia Pacific. For more information about Stage
Three, please refer to:

Last /8 address policy

IPv4 requests will now be assessed under section 9.10 in “Policies
for IPv4 address space management in the Asia Pacific region”:

APNIC’s objective during Stage Three is to provide IPv4 address space
for new entrants to the market and for those deploying IPv6.

>From now, all new and existing APNIC account holders will be entitled
to receive a maximum allocation of a /22 from the Final /8 address

For more details on the eligibility criteria according to the Final /8
policy, please refer to:

Act NOW on IPv6

We encourage Asia Pacific Internet community members to deploy IPv6
within their organizations. You can refer to APNIC for information
regarding IPv6 deployment, statistics, training, and related regional
policies at:

Announcements IPv6

IPv6 Dynamic DNS Now Available

We’ve released a minor update to our Dynamic DNS client to support IPv6. We’ve been working on this on and off for the last few months but didn’t really put any kind of rush on it because we didn’t believe that there was any demand for such a service.

Today though a question about IPv6 enabled dynamic DNS services came up on the ipv6-ops list, so we went ahead and finished it up for public consumption. It’s still business as usual for everyone using it for IPv4 dynamic DNS, but now there’s an IPv6 option. See the documentation for details. We have not added an AAAA record to, so while there is auto-detect code for IPv6 clients in our Dynamic DNS client, there’s no way to take advantage of it just yet.

If anyone actually uses it for its IPv6 support we’d be interested in your feedback.

IPv6 Status

Global Crossing IPv6 Trouble

An issue with a customer’s IPv6 access was brought to our attention this morning. After some basic testing, it was apparent the traceroutes were stopping at our Global Crossing PE router (provider side) and we opened a trouble ticket with them to investigate.

A few hours later we discovered that the RIPE website was unreachable. Although the traceroute out indicated it was leaving our network via Sprint, we suspected the return traffic was trying to reach us via Global Crossing. After withdrawing our route announcements to GC we were able to reach RIPE and the customer who origionally brought the issue to our attention.

As this time we are waiting for a resolution on our trouble ticket with Global Crossing regarding this issue.

UPDATE [2011-03-06]: Global Crossing acknowledges that some recent MPLS changes in their network had caused our IPv6 to be null routed. They reverted the most recent changes and connectivity was restored. We will continue to monitor the situation.


Free Pool of IPv4 Address Space Depleted

The final five IPv4 allocations go to:

102/8   AfriNIC    2011-02 ALLOCATED
103/8   APNIC      2011-02   ALLOCATED
104/8   ARIN       2011-02    ALLOCATED
179/8   LACNIC     2011-02  ALLOCATED
185/8   RIPE NCC   2011-02    ALLOCATED

The Number Resource Organization (NRO) announced today that the free pool of available IPv4 addresses is now fully depleted. On Monday, January 31, the Internet Assigned Numbers Authority (IANA) allocated two blocks of IPv4 address space to APNIC, the Regional Internet Registry (RIR) for the Asia Pacific region, which triggered a global policy to allocate the remaining IANA pool equally between the five RIRs. Today IANA allocated those blocks. This means that there are no longer any IPv4 addresses available for allocation from the IANA to the five RIRs.

To read the full text of this announcement from the NRO, go to:


Two /8s allocated to APNIC from IANA (39/8 and 106/8)

Following these allocations an “end game” policy will now be triggered in which the final five /8s will be automatically distributed, one to each region, marking the end of IPv4 allocations to regional registries. Read the full announcement from APNIC below. We expect there will be a another announcement when the last /8s are allocated and we’ll pass it along.

UPDATE: Significant Announcement 3 February – Watch it live!

Dear Colleagues

The information in this announcement is to enable the Internet
community to update network configurations, such as routing filters,
where required.

APNIC received the following IPv4 address blocks from IANA in February
2011 and will be making allocations from these ranges in the near


Reachability and routability testing of the new prefixes will commence
soon. The daily report will be published at the usual URL:

Please be aware, this will be the final allocation made by IANA under
the current framework and will trigger the final distribution of five
/8 blocks, one to each RIR under the agreed “Global policy for the
allocation of the remaining IPv4 address space”.

After these final allocations, each RIR will continue to make
allocations according to their own established policies.

APNIC expects normal allocations to continue for a further three to six
months. After this time, APNIC will continue to make small allocations
from the last /8 block, guided by section 9.10 in “Policies for IPv4
address space management in the Asia Pacific region”. This policy
ensures that IPv4 address space is available for IPv6 transition.

It is expected that these allocations will continue for at least
another five years.

APNIC reiterates that IPv6 is the only means available for the
sustained ongoing growth of the Internet, and urges all members of the
Internet industry to move quickly towards its deployment.
