ICANN Ratifies Global Policy for Allocation of IPv6 Addresses

At its September 7, 2006 Meeting the Board of ICANN ratified a global policy for the allocation of IPv6 addresses by the Internet Assigned Numbers Authority (IANA) to Regional Internet Registries.

IPv6 is the next generation Internet Protocol (IP) addressing scheme. Internet protocol addresses are the unique numerical identifiers used to identify each computer on the Internet, so that Internet data is transmitted to the correct destination. The introduction of IPv6 has greatly expanded the number of IP addresses available for the world to use.

"This is an outcome which provides certainty to Internet Registries and their customers who include Internet Service Providers and users" said Dr Paul Twomey, President and CEO of ICANN.

"It addresses concerns about the method for future allocations of Internet address space and ensures projected demand can be met for many years to come", he said.

ICANN is responsible for IANA, which coordinates the world-wide IP address space.

"This was developed through the ICANN community's bottom up consensus approach which saw IPV6 adopted as a policy development process. That means ICANN's stakeholders and constituencies have shaped this policy from day one" Dr Twomey said.

"On behalf of the Board I congratulate all those that worked for this outcome" he said.

About ICANN:

ICANN is a non-profit organisation responsible for coordinating the Internet's systems of unique identifiers, including the systems of domain names and numeric addresses that are used to reach computers on the Internet. ICANN's mission is to ensure the stable and secure operation of these unique identifier systems, which are vital to the Internet' operation. In addition, ICANN coordinates policy development related to these technical functions through its effective bottom-up consensus model.

Domain Name System
Internationalized Domain Name ,IDN,"IDNs are domain names that include characters used in the local representation of languages that are not written with the twenty-six letters of the basic Latin alphabet ""a-z"". An IDN can contain Latin letters with diacritical marks, as required by many European languages, or may consist of characters from non-Latin scripts such as Arabic or Chinese. Many languages also use other types of digits than the European ""0-9"". The basic Latin alphabet together with the European-Arabic digits are, for the purpose of domain names, termed ""ASCII characters"" (ASCII = American Standard Code for Information Interchange). These are also included in the broader range of ""Unicode characters"" that provides the basis for IDNs. The ""hostname rule"" requires that all domain names of the type under consideration here are stored in the DNS using only the ASCII characters listed above, with the one further addition of the hyphen ""-"". The Unicode form of an IDN therefore requires special encoding before it is entered into the DNS. The following terminology is used when distinguishing between these forms: A domain name consists of a series of ""labels"" (separated by ""dots""). The ASCII form of an IDN label is termed an ""A-label"". All operations defined in the DNS protocol use A-labels exclusively. The Unicode form, which a user expects to be displayed, is termed a ""U-label"". The difference may be illustrated with the Hindi word for ""test"" — परीका — appearing here as a U-label would (in the Devanagari script). A special form of ""ASCII compatible encoding"" (abbreviated ACE) is applied to this to produce the corresponding A-label: xn--11b5bs1di. A domain name that only includes ASCII letters, digits, and hyphens is termed an ""LDH label"". Although the definitions of A-labels and LDH-labels overlap, a name consisting exclusively of LDH labels, such as"""" is not an IDN."
