Comment Regarding Two-Character Letter/Letter Label Request

To post a comment to a request, complete the form below. Step 1 requires the letter/letter label (e.g., aa, ab, ac) for which the comment is submitted, as well as information regarding the commenter. Step 2 requires selection of the gTLD for which the comment is submitted, and an explanation of how release of the label from reservation would create confusion with the related government’s corresponding country code. Multiple gTLDs may be selected. 

Comments are to be submitted while the 60-day public comment period is open for the corresponding gTLD or they might not be considered. If a comment is submitted for a letter/letter two-character label that has previously been authorized for release for the gTLD, the comment will not be considered. 

Comments will be reviewed and considered by ICANN to determine whether to authorize the release of the requested Letter/Letter Two-Character ASCII Label. During ICANN’s consideration, ICANN will evaluate whether the comment is from the related government and pertains to confusion with its corresponding country code; if the comment is not from the related government and/or does not pertain to confusion its corresponding country code, ICANN might authorize the letter/letter label for release.

Please input the verification code, and your comment will be published. If you do not receive the verification code within one hour, we encourage you to check your spam folder.

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."
