Try out our new IANA site

Beta ScreenshotOne thing that has been obvious for quite some time is the IANA web site needed some attention. Somewhat of a relic of an earlier era of the Internet, the web site had grown into a pile of information that is poorly organised and hard to navigate.

Last year, we shared some concepts with the community on how we’d like to improve it. First and foremost was making IANA’s purpose clear, and its key information easy to find. Based on the initial feedback, we are almost ready to launch a completely new IANA web site.

We have literally begun from scratch. All web pages have been rewritten, and their place on the website rethought. We are working towards fully standards compliant pages that work in many different browsers. We have also tried to lay a foundation so we can much more easily add new materials and features to the IANA website once it is launched.

So now that we have almost finished the conversion of the site, it is a great opportunity to offer a sneak peek and gather feedback on the almost final product. Our aim is to integrate your feedback, as well as tidy up the remaining rough edges, over the next few weeks. Once we are confident everything is working, we will then replace the existing IANA site.

The new site is at Take a look and tell us what you think in the comment area below.


    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."
