Les AAAA des serveurs racine DNS sont enfin publies

Addition enhances end-to-end connectivity for IPv6 networks

4 February 2008

MARINA DEL REY, Calif.: The Internet Corporation for Assigned Names and Numbers today took another step along the path of deployment for the next-generation IPv6 Internet addressing system.

IPv6 addresses were added for six of the world’s 13 root server networks (A, F, H, J, K, M) to the appropriate files and databases. This move allows for the possibility of fuller IPv6 usage of the Domain Name System (DNS). Prior to today, those using IPv6 had needed to retain the older IPv4 addressing system in order to be able to use domain names.

"The ISP community welcomes this development as part of the continuing evolution of the public Internet,” said Tony Holmes, chair of ICANN’s Internet Service and Connectivity Provider Constituency. “IPv6 will be an essential part our future and support in the root servers is essential to the growth, stability, and reliability of the public Internet.”

Name server software relies on the root servers as a key part in translating domains like “icann.org” into the routing identifiers used by computers to connect to one another. In 2007 the ICANN Security and Stability Advisory Committee concluded that ICANN should move forward with the enhancement of the DNS root service by adding IPv6 addresses for the root servers.

As more and more devices connect to the Internet they require unique Internet Protocol (IP) addresses. The remaining free pool of unassigned IPv4 addresses is being depleted by the growth of the Internet. IPv6 is the addressing protocol that increases the unique IP addresses from the 4 billion available in IPv4, to more than 340 trillion trillion trillion.

“Today’s addition of IPv6 addresses for the root servers enhances the end-to-end connectivity for IPv6 networks, and furthers the growth of the global interoperable Internet,” added David Conrad, ICANN’s Vice President of Research and IANA Strategy. “This is a major step forward for IPv6-only connectivity and the global migration to IPv6.”

About ICANN:

ICANN is responsible for the global coordination of the Internet's system of unique identifiers like domain names (like .org, .museum and country codes like .uk) and the addresses used in a variety of Internet protocols that help computers reach each other over the Internet. Careful management of these resources is vital to the Internet's operation, so ICANN's global stakeholders meet regularly to develop policies that ensure the Internet's ongoing security and stability. ICANN is an internationally organized, public benefit non-profit company. For more information please visit: www.icann.org .

About IANA:

The Internet Assigned Numbers Authority (IANA) is the body responsible for coordinating some of the key elements that keep the Internet running smoothly. Whilst the Internet is renowned for being a worldwide network free from central coordination, there is a technical need for some key parts of the Internet to be globally coordinated – and this coordination role is undertaken by IANA.
IPv6 Address Added for Root Servers in the Root Zone

 IPv6 Addresses for the Root Servers
29 January 2008

On or about 4 February 2008, for the first time AAAA records for some of the authoritative name servers for the DNS root zone will be introduced. These records will provide for access to the root servers over IPv6 transport, and will be implemented in both the root zone data, and the root hints file. We are providing this advanced notification in case unexpected network events occur that might be related to this change.

Six of the thirteen listed authorities for the root zone will add an AAAA record, as follows:

Authority IPv6 Address Prefix Length*
A.ROOT-SERVERS.NET 2001:503:ba3e::2:30 /48
F.ROOT-SERVERS.NET 2001:500:2f::f /48
H.ROOT-SERVERS.NET 2001:500:1::803f:235 /48
J.ROOT-SERVERS.NET 2001:503:c27::2:30 /48
K.ROOT-SERVERS.NET 2001:7fd::1 /32
M.ROOT-SERVERS.NET 2001:dc3::35 /32


Operators who employ prefix filtering should verify that their routing policy does not prohibit access to these addresses.
