If you build it, they will come

As you would expect, most of ICANN’s external services, including this blog, are available over IPv6 as well as IPv4. And at the request of the ICANN Board, a regular comparative measure of IPv6 use at the ICANN and IANA websites has been provided to them for months.  The good news is that the trend from the measurement shows an increase in the use of the ICANN and IANA web sites using IPv6. IPv6 hits on our web sites in June were about 1.7% of all hits.

The peaks in IPv6 access, which is shown in red on the graph, closely correlate with ICANN meetings. IPv6 connectivity is provided as standard at ICANN meetings and lots of meeting attendees have been using it without knowing while using the free WiFi.

So, as the graph shows, we have had peaks in IPv6 access alongside the October 2009 ICANN meeting in Seoul, the March 2010 ICANN meeting in Nairobi and June’s ICANN meeting in Brussels. There was also a peak in January 2010, which we believe is associated with the IANA Business Continuity Exercise that took place on the 19th of January, thus users were preferring the IPv6 transport while IPv4 provision was in flux.

What is perhaps more heartening than the peaks associated with the ICANN meetings, is that the troughs in April and May 2010 are far less shallow than those seen in December 2009 and February 2010. There is growth in IPv6 traffic! While at the start of the process we had to use a magnifying lens to see the changes, they are definitely becoming more obvious.

ICANN will continue to assess the adoption of IPv6 worldwide and make reports at regular intervals. ICANN also encourages all organizations to make sure they are – or will be – implementing IPv6 on their networks.

    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""icann.org"" is not an IDN."
