Public Comment: Initial Report on Fast Flux Hosting

This page is available in:

A public comment period opens today for 20 days on an Initial Report on Fast Flux Hosting.

In May 2008, the GNSO Council initiated a Policy Development Process (PDP) and called for the creation of a working group on fast flux. The working group was asked to consider the following questions:

  • Who benefits from fast flux, and who is harmed?
  • Who would benefit from cessation of the practice and who would be harmed?
  • Are registry operators involved, or could they be, in fast flux hosting activities? If so, how?
  • Are registrars involved in fast flux hosting activities? If so, how?
  • How are registrants affected by fast flux hosting?
  • How are Internet users affected by fast flux hosting?
  • What technical (e.g. changes to the way in which DNS updates operate) and policy (e.g. changes to registry/registrar agreements or rules governing permissible registrant behavior) measures could be implemented by registries and registrars to mitigate the negative effects of fast flux?
  • What would be the impact (positive or negative) of establishing limitations, guidelines, or restrictions on registrants, registrars and/or registries with respect to practices that enable or facilitate fast flux hosting?
  • What would be the impact of these limitations, guidelines, or restrictions to product and service innovation?
  • What are some of the best practices available with regard to protection from fast flux?

The Group was also tasked to obtain expert opinion, as appropriate, on which areas of fast flux are in scope and out of scope for GNSO policy making.

The Fast Flux Working Group started its deliberations in June 2008 and has now published an Initial Report. In this report, the Working Group has provided initial answers to the charter questions, has drawn interim conclusions and has provided a number of ideas for next steps for discussion and feedback during the public comment period. It should be noted that at this stage the Working Group has not reached consensus on any of the ideas for next steps outlined in the report. The objective of the Working Group will be to review the input received during the public comment period and determine which, if any, of the proposed next steps receive the support of the Working Group for inclusion in the final report.

As stated in the ICANN Bylaws, the Initial Report is posted for public comment for 20 days. The comments received will be analyzed for redrafting of the Initial Report into a Final Report to be considered by the GNSO Council for further action.

The Working Group would like to encourage everyone to review the complete Initial Report [PDF, 1,210K] before submitting comments.

Comments on the Initial Report should be sent to

The deadline for submission of comments is 15 February 2009.

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."
