Full summary
This video provides a detailed explanation of how to use cloud subscription services (mistakenly labeled as 'cloud' in the text) long-term and stably by leveraging technical methods. The core principle lies in circumventing Anthropic's risk management (risk control) mechanisms—specifically, avoiding collective liability due to the same IP address, as well as ensuring that digital fingerprints such as timezone, language, DNS, IPv6, and others do not reveal the true geographical location. The practical steps are divided into three stages: 1) Renting a pure, reliable overseas cloud server (New York node in the United States is especially recommended), and setting up a proxy relay environment; 2) Installing the Clash client on your local device and enabling "virtual network adapter (TUN mode)" to force all traffic to be routed through the proxy; 3) Cleansing system-level network fingerprints (disabling IPv6, manually setting the time to UTC-4, changing DNS to Cloudflare (1.1.1.1), and setting browser language to English). Regarding account operation strategy, the following points are emphasized: using Google accounts or custom domain email addresses for new account registration is recommended; nurturing the account under the Pro plan for several months during initial stages; strictly adhering to the isolation strategy of "one account per device"; maintaining surplus capacity; and keeping multiple sub-accounts ready. The author has personally tested this setup for over a year and confirmed that no issues—including account bans—have occurred, even when using Chinese-language conversations or operating from timezones outside the United States.
1. General Principles: Purpose and Core Risk Management Logic
- Objective: All items displayed on Claude’s verification page (fingerprint verification page) must turn green (i.e., all fingerprint checks pass).
- Main Risk Factor: If users within the same IP segment have been blocked, other users may also suffer collateral damage due to the "IP accountability" mechanism.
- Core Countermeasure: The communication exit must be exclusively and solely a clean, dedicated overseas server IP.
2. Step One: Renting a Pure Overseas Cloud Server
- Recommended Region: United States (especially New York)—high network stability and high IP cleanliness.
- Selection Criteria: Low monthly cost, supports Alipay payment, provides pure and exclusive IP addresses.
- Deployment Steps: Select Simplified Chinese → Deploy virtual machine → Set region to New York, USA → Choose "Control panel-free (lightweight version)" for OS → Use Alipay for payment → Start the server.
3. Step Two: Testing and Optimizing Server IP Quality
- Testing Method: Copy the server’s IP → Access an online speed test site → Enter the IP and perform a direct connection test.
- Causes of Issues: In some mainland Chinese regions, direct connection speed may be slow or fail.
- Remedies: Submit a support ticket requesting IP replacement, or migrate to another cloud service such as AWS or DigitalOcean.
4. Step Three: Configuring the Server as a Proxy Relay Node
- Connection Method: Run SSH command on the terminal (
ssh root@<IP>) → Paste password (cursor won’t show, but input is valid). - Script Deployment: Obtain one-click deployment command from an open-source project → After execution, a red V2Ray subscription link (subscription URL) will be generated → This must be saved.
5. Step Four: Local Client Configuration (Clash for Windows)
- Installation: Visit GitHub Releases page → Download and install Clash for Windows according to your operating system.
- Subscription Import: Use an online tool to convert the V2Ray link into a YAML-formatted subscription file → After downloading, import it into Clash → Assign a name and enable it.
- Key Setting: Always enable "Virtual Network Adapter (TUN mode)" → Force all system traffic to be routed through the proxy.
6. Step Five: System-Level Network Fingerprint Sanitization
- Disable IPv6: Open network connection properties → Uncheck "Internet Protocol Version 6 (TCP/IPv6)" → Reload the verification page and confirm IPv6 has disappeared.
- Timezone Synchronization: Disable automatic timezone detection → Manually set to "Atlantic Standard Time (UTC-4)" → Enable automatic daylight saving time adjustment.
- DNS Change: Browser settings → Enable "Secure DNS" → Select Cloudflare (1.1.1.1) as the service provider.
- Language Cleanup: Browser language settings → Remove all Chinese languages → Keep only English → Reload the verification page.
7. Verification and Usage Guidelines
- Verification Criteria: All color blocks on the Claude verification page (IP, DNS, timezone, language) must turn green.
- Usage Requirement: Before accessing the official Claude website or launching the app, verify that the validation page shows all green after each PC startup/reboot.
- Notes: The server’s IP is a "data center IP," different from residential broadband. However, based on the author’s personal testing, there has been absolutely no impact over a full year.
8. Claude Account Registration Strategy
- Recommended Approach: Use a newly created Google account (to avoid risks associated with existing accounts).
- Key Conditions: IP, timezone, language, and DNS must all be clean → Skip SMS verification and knowledge-based security checks (KS), allowing direct login.
- Alternative Option: Use your own domain email (e.g., name@yourdomain.com) → Enables infinite inbox generation → Improves reliability.
9. Practical Operation: Activating Subscription on Android Devices
- Environment Setup: The smartphone must be connected via an American network environment (e.g., through proxy).
- Google Play Settings: Set country/region to the United States → Link a Mastercard that supports foreign currency payments.
- Subscription Process: Within the Claude app → Top-left menu → Avatar → Upgrade → Trigger the Google Play payment channel.
10. Fundamental Principle for Long-Term Stable Operation: Environmental Isolation
- Recommended Platform: Windows Hyper-V virtual machine (completely isolated from host machine).
- Minimum VM Configuration: Install only browser, VS Code, and the Claude desktop client → Do not install any unnecessary software.
- Environmental Consistency: Set the virtual machine’s timezone to U.S. time and the OS language to English → Strictly enforce the rule of "one account per device."
- Behavioral Norms: Do not switch accounts, do not connect to domestically produced devices, do not mix with other AI tools.
11. Account Development Strategy
- Development Period: After free account registration, engage in conversations at intervals of several days to weeks, continuing for several months → Then upgrade to Pro plan.
- Usage Moderation: Maintain 20%–30% quota surplus each month → Avoid exhausting quotas → Continue regular conversations via the web version.
- Premium Path: After several months of stable use on the Pro plan, upgrade to Max → Avoid abrupt actions.
12. Risk Response Plan and Clarification of Common Misunderstandings
- Preparatory Measures: While operating the primary account, simultaneously nurture 2–3 sub-accounts as backups.
- Clarification of Misconceptions: Restrictions such as "only usable during daytime in U.S. time" or "must communicate in English" are not absolute. The author and numerous users have successfully used China Standard Time (CST) + Chinese-language conversations without ever experiencing account bans.
