IVPN: Why China Blocks This Gibraltar-Based VPN Service

What IVPN Is

IVPN is a VPN service founded in 2010 and based in Gibraltar. The service is operated by Privatus Limited, a Gibraltar-registered company. IVPN serves a global user base numbering in the tens of thousands, with a documented emphasis on privacy-first infrastructure: the service does not log user activity, maintains minimal data collection, and publishes regular transparency reports. The service runs servers in multiple jurisdictions and offers both OpenVPN and WireGuard protocol options.

Why It's Censored

China's blocking of IVPN stems from the Chinese government's broader policy on VPN services. The Ministry of Industry and Information Technology (MIIT) and the Cyberspace Administration of China (CAC) have, since 2015, enforced regulations requiring all VPN use to be government-licensed. Unauthorized VPN services—which includes nearly all commercial offshore providers—are classified as tools that circumvent state control over information flows.

China's regulatory framework, particularly CAC directives issued in 2017, explicitly targets VPN applications and services that enable access to blocked content. IVPN, like other uncensored VPN providers, directly contradicts this mandate because it provides users a means to bypass the Great Firewall without government oversight. The service makes no special accommodation for Chinese users and does not operate licensed local infrastructure, making it a clear regulatory target.

Similar restrictions exist in Iran, where the Ministry of Communications and Information Technology (MCIT) blocks unauthorized VPNs, though Iran's enforcement is often inconsistent. Russia has also increasingly targeted VPN providers since 2017 legislation banned unregistered proxy and anonymization tools, though enforcement remains uneven.

Technical Blocking Methods

China employs multiple overlapping techniques to block IVPN access. DNS filtering is the first layer: known IVPN domain names are redirected or returned as non-existent. IP-based blocking targets known IVPN server addresses through deep packet inspection (DPI) systems operated by state-controlled ISPs, which identify and drop traffic to flagged IP ranges.

More sophisticated blocking uses SNI (Server Name Indication) filtering, where packets containing IVPN domain names in the TLS handshake are dropped before the connection completes. China's GFW also employs active probing, deliberately connecting to suspected VPN servers to fingerprint their behavior and add them to block lists.

Iran uses broadly similar DNS and IP-blocking methods but with less consistent DPI-based filtering. Russia's blocking tends to focus on known IP addresses and domain names rather than protocol-level detection.

User Workarounds

Users in censored regions employ several general tactics. Obfuscation protocols mask VPN traffic to appear as regular HTTPS traffic, making DPI detection harder. Changing DNS servers to non-Chinese resolvers can bypass simple DNS filtering, though this is increasingly ineffective as ISP-level blocking tightens.

Bridge servers—intermediate proxies that connect users to the main VPN network—can bypass IP-based blocking if the bridge addresses are not yet documented. Switching between VPN protocols or port numbers may work temporarily, though Chinese authorities regularly test and block new configuration combinations.

Alternatives

Other offshore VPN services face similar Chinese blocking. WireGuard-based providers operating from non-Five Eyes jurisdictions experience the same obfuscation and IP-blocking tactics. Open-source VPN tools like OpenVPN with custom builds sometimes evade detection longer than branded commercial services, though blocking is eventual.

Proton-based services and other established providers are also blocked in China; no major VPN escapes indefinitely.

Outlook

China's blocking has intensified since 2017 and shows no signs of easing. The government treats VPN blocking as infrastructure maintenance, regularly updating block lists and deployment techniques. The technological cat-and-mouse game continues, but the trend is consolidation of control, not liberalization. IVPN's users in affected regions should expect ongoing disruption and prepare contingency access methods.
