16.1 Supporting Issue for Chinese Domain Name (CDN)

16.1.1 Browser

Issue: The old version for the mainstream browser does not support CDN, such as Opera (Version below 9.2), Firefox (Version below 2.0), Internet Explorer (Version below 7) and Safari (Version below 3.1).

Solution: China Internet Network Information Center (CNNIC) will propagandize with the software companies of the browser to Internet users to use the browser version which supports the Internationalized Domain Name (IDN).

16.1.2 Email Issue

Issue: The current protocol of electronic mail and the application programs do not support CDN.

Solution: CNNIC founded Email Address Internationalization (EAI) working group guided by Internet Engineering Task Force (IETF) in 2006, formulating the email related protocols which support the IDNs including CDNs. Presently, the working group has completed three standard track RFCs associated with the core EAI protocol: RFC 6531 (mainly conducted by CNNIC), RFC 6532, RFC 6533. CNNIC aims to actively motivate the achievement of the EAI related application and for commercial use through the successive plans.

16.1.3 Registration Data Directory Services (RDDS)

Issue: According to Whois protocol of RFC 3912, only ASCII encoding is suggested to be adopted by RDDS, which thus is not necessary to support Chinese domains.

Solution: RDDS adopts UTF-8 encoding format with the query information supporting both English and Chinese. We have joined in the associated standardization and testing work of IETF Whois-based Extensible Internet Registration Data Service (Weirds). We will give a priority to upgrade toward replacement RDDS technologies accredited by ICANN in the future.

16.2 Supporting Issue for the Equivalence of the Simplified, Traditional and Variant Chinese

Issue: The simplified, traditional and variant CDNs should be registered to the same registrant to ensure the equivalence.


(1) According to the principles of RFC 3743 and RFC 4713, CNNIC drew up the registration policy for the simplified, traditional and variant CDNs: When registrants register the original domain names, we give them full simplified and traditional CDNs on a free-of-charge basis and reserve all the variant domains.

(2) Shared Registration System (SRS) deploys the registration extension of CDN variants based on Extensible Provisioning Protocol (EPP) in accordance with RFC 3735 to support the bundle registration of variant CDN and ensures the accordant operation for the CDN of the same bundle.

16.3 Mixed Directionality

Issue: Problems have been identified in strings with characters of mixed right-to-left and left-to-right directionality when numerals are adjacent to the path separator (i.e., the dot).

Solution: To avoid the occurrence of this problem, CNNIC formulated the associated registration policy that with the exception of IDN registration of the right-to-left, CDN is exclusively permitted for ʺ.公司ʺ registration.
