CNNIC

Overview

CNNIC (China Internet Network Information Center) was founded in 1997 and is headquartered in Beijing. It is the official registry for .cn, China's country-code top-level domain (ccTLD), and serves as the core institution of China's internet infrastructure. CNNIC manages domain registration, IP address allocation, AS number management, and publishes authoritative China Internet development statistics.

.cn is the world's largest ccTLD, with over 21 million registered domains as of 2026—far surpassing the second-ranked .de (Germany, ~17.7M). CNNIC also operates Chinese IDN top-level domains including .中国 (China), .公司 (Company), and .网络 (Network), enabling fully Chinese-script domain names. CNNIC is an active participant in the ICANN Governmental Advisory Committee (GAC), representing China in global internet governance.

Key Strengths

• World's Largest ccTLD Operation: With 21M+ registered domains, .cn ranks first among all ccTLDs globally. For websites targeting the Chinese market, a .cn domain is not only a compliance requirement but also improves domestic access speed and search engine indexing priority.
• Leading Chinese IDN Support: CNNIC was among the first registries worldwide to deploy Chinese-script top-level domains at scale. .中国, .公司, and .network enable Chinese users to enter website addresses in their native language, offering unique brand marketing and user experience value.
• National Authority Status: CNNIC was established under China's Ministry of Information Industry (now MIIT) as the statutory .cn domain manager. Its certified registrar system ensures standardized and legally compliant domain registration procedures.
• Authoritative Internet Research: CNNIC's biannual China Internet Development Statistics Report covers internet user demographics, e-commerce, mobile internet, and other core metrics—the most authoritative reference for China's digital economy.
• Regulatory Compliance Assurance: .cn domain registration fully complies with Chinese laws including the Internet Domain Name Management Measures and Cybersecurity Law. For businesses operating legally in China, .cn domains are an essential component of the compliance framework.

Product Ecosystem

.cn Domain Registration Management

CNNIC manages .cn domain registration, renewal, transfer, and deletion through its certified registrar network. Supports .cn (second-level, e.g., example.cn) and third-level domains such as .com.cn, .net.cn, .org.cn, and .gov.cn. Both individuals and enterprises can register .cn domains subject to real-name verification completion. .gov.cn is restricted to government agencies only.

Chinese IDN Domain Services

CNNIC operates three Chinese top-level domains: .中国, .公司, and .网络, plus Chinese second-level domains under .cn. Chinese IDN domains use Punycode encoding for storage while browsers display the Chinese characters natively. For brands targeting Chinese consumers, Chinese-script domains offer significant memorability and communication advantages.

IP Address and AS Number Allocation

As a National Internet Registry (NIR) authorized by APNIC, CNNIC manages the allocation of IPv4, IPv6 addresses and Autonomous System (AS) numbers within China, serving as the central authority for China's internet address resources.

Internet Statistics and Research

CNNIC publishes the China Internet Development Statistics Report (semi-annual) plus specialized reports on mobile internet, e-commerce, online payments, video streaming, and other sectors—serving as the primary data source for China's internet industry.

Limitations

• Cumbersome Real-Name Verification: Individual .cn domain registrants must upload government-issued ID (national ID card, passport) and complete online verification. Enterprises must provide business licenses. This process adds hours to days compared to instant .com/.net registration.
• Higher Pricing Than gTLDs: .cn registration and renewal prices are generally higher than .com (~$8-12/year), with some registrars charging $20-50/year for .cn domains. Renewal prices often significantly exceed first-year promotional rates.
• International Trust Perception: Due to China's internet content restrictions and data compliance requirements, some international users and businesses have reservations about using .cn domains. International-facing websites may be better served by .com or local ccTLDs.
• Regulatory Change Risk: .cn registration rules and management policies may change with Chinese laws and regulations, such as enhanced real-name requirements or keyword registration restrictions. Businesses need to monitor policy developments to ensure ongoing compliance.
• Expired Domain Squatting Legacy: Due to extremely low early registration costs, a significant number of .cn domains were bulk-registered and subsequently expired. Released domains include SEO spam sites and parked pages, somewhat diluting the .cn namespace's overall quality perception.

Use Cases

• Chinese Enterprise Websites (★★★★★): Corporate brands targeting the Chinese market. A .cn domain is essential for compliance and improves domestic user access speed and trust.
• Government & Public Institutions (★★★★★): .gov.cn is the standard suffix for Chinese government websites and is restricted to authorized government agencies.
• China-Facing E-Commerce Platforms (★★★★★): E-commerce, content platforms, and service websites operating in China require .cn domains for ICP filing and network compliance.
• Foreign Enterprises in China (★★★★): Multinational corporations with Chinese operations register .cn domains for localized branding, ensuring registration through their Chinese entity for real-name verification.
• Personal Websites & Blogs (★★★★): Chinese individual users establishing blogs, portfolios, or personal brands benefit from .cn's affordability and fast domestic access.

FAQ

• Is real-name verification mandatory for .cn domains? Yes. Under China's Internet Domain Name Management Measures, all .cn domains (including .中国, .公司, .网络) require real-name verification. Individuals must provide a national ID card; enterprises must provide a business license. Domains without verified status will have DNS resolution suspended. Chinese domain registration guide

• Can foreigners register .cn domains? Yes. CNNIC permits non-Chinese citizens to register .cn domains, but real-name verification is still required—foreigners can use passports or equivalent identification documents. However, the verification process and ongoing regulatory requirements make .cn registration more complex than .com for foreign registrants. ccTLD domain selection strategy

• Is ICP filing the same as domain real-name verification? No, these are separate steps. Domain real-name verification occurs during registration. ICP filing (recordal with MIIT) is a second compliance step required when hosting a website on servers within mainland China, regardless of which domain extension is used. ICP filing guide for websites

• What's the difference between .cn and .中国? Technically both are CNNIC-operated TLDs. .cn is the ASCII country-code domain; .中国 is the IDN (internationalized) version, visually more intuitive for Chinese users. Registering a .中国 domain automatically reserves the corresponding .cn domain (e.g., 示例.中国 maps to xn--fsq..cn), and vice versa. .中国 pricing is typically slightly higher than .cn. TLD comparison

• How do I check if a .cn domain is available? Use CNNIC's official WHOIS lookup tool or registrar domain search pages. Note that .cn WHOIS data displays registrant information according to Chinese regulations, with some personal data protected under privacy policies. WHOIS privacy and GDPR guide
