What is an overseas proxy IP? What is the principle of an overseas proxy IP?

The principle of overseas proxy IP is based on the working principle of proxy server, which is an intermediate server that acts as a medium between the user and the target server. Here is how overseas proxy IP works:

• Client connects to the proxy server: The user's device (such as a computer, smartphone, or router) first connects to a proxy server located overseas. This can be done by configuring network settings or using a specific proxy application.
• Sending requests to a proxy server: When users try to access a website or use an Internet service, their requests are not sent directly to the target server but to a proxy server.
• Proxy server processes the request: After the proxy server receives the user's request, it will make a new request on behalf of the user to obtain the required content or service. This new request is sent to the target server.
• The proxy server returns a response: Once the proxy server gets a response from the target server, it returns the response to the user's device.
• User device receives response: Finally, the user's device receives the response from the proxy server and displays or processes it as if it was obtained directly from the target server.

Key points of working principle:

• IP address hiding: A proxy server acts as an intermediary between the user and the target server, so the target server only sees the proxy server's IP address instead of the user's real IP address. This helps users hide their identity and location.
• Geolocation spoofing: By connecting to a proxy server located overseas, users can disguise their geographic location. For example, if a user is located in China but connects to a proxy server in the United States, their IP address will appear as the United States, allowing them to access content or services restricted to the United States.
• Access Control: A proxy server can be used to bypass Internet access restrictions or censorship because it can access the target server and return content regardless of the user's region.
• Privacy protection: Proxy servers can increase the user's online privacy because they do not directly expose the user's real IP address. This is very useful for anonymous browsing and protecting privacy.

It is important to note that proxy servers can be public proxy servers (open proxies, no authentication required) or private proxy servers (authentication or subscription required). Private proxy servers generally offer better performance and privacy protection, but require payment.
