域名注册管理后端应急运行机构,又称 EBERO,是新 gTLD 项目的一项重要创新。EBERO 项目可在新 gTLD 运行机构发生故障时,缓和该故障对域名系统安全性和稳定性所带来的风险。


  1. 针对注册域名的域名系统解析
  2. 共享注册系统的运营
  3. 注册数据目录服务的运营(例如:WHOIS)
  4. 注册数据托管存储
  5. 根据 DNSSEC 的要求维护一个已经适当签名的根区

EBERO 的服务范围是有限的。例如,EBERO 将不会提供顶级域名运行机构可能向其客户提供的额外服务,例如:网络托管或网络分析。


ICANN 负责宣布需要激活 EBERO 应急服务的事件,并负责协调所有应急响应活动。



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."
