| What is IPv6 |
| Internet Protocol version 6 (IPv6)
is the next-generation Internet Protocol version designated
as the successor to version 4. IPv4, the first
implementation used in the Internet and still in dominant
use currently. It is an Internet Layer protocol for
packet-switched internetworks. The main driving force for
the redesign of Internet Protocol was the foreseeable IPv4
address exhaustion. IPv6 was defined in December 1998 by the
Internet Engineering Task Force (IETF) with the
publication of an Internet standard specification,
RFC 2460. |
| IPv6 has a much larger address space than
IPv4. This results from the use of a 128-bit address,
whereas IPv4 uses only 32 bits. The new address space thus
supports 2128
(about 3.41038) addresses. This expansion
provides flexibility in allocating addresses and routing
traffic and eliminates the primary need for network
address translation (NAT), which gained widespread
deployment as an effort to alleviate IPv4 address
exhaustion. |

| IPv4 Exhaustion |
| Estimates of the time
frame until complete exhaustion of IPv4 addresses
used to vary widely. In 2003, Paul Wilson (director
of
APNIC) stated that, based on then-current rates
of deployment, the available space would last for
one or two decades.In September 2005 a report by
Cisco Systems suggested that the pool of available
addresses would dry up in as little as 4 to 5 years.
As of May 2009, a daily updated report projected
that the
IANA pool of unallocated addresses would be
exhausted in June 2011, with the various Regional
Internet Registries using up their allocations from
IANA in March 2012. There is now consensus among
Regional Internet Registries that final milestones
of the exhaustion process will be passed in 2010 or
2011 at the latest, and a policy process has started
for the end-game and post-exhaustion era. |

Indonesia IPv6 Task Force support
for IPv6 |
Native IPv6 connectivity is
available for both direct connection customers and
colocation customers. APJII also provides a
free
IPv6 tunnel broker
via Indonesia IPv6 Task Force which allows users to experiment and research
with IPv6 by tunneling over the existing IPv4
Internet. Indonesia IPv6 Task Force tunnel broker is available for
use by anybody.
