With the development of Internet technology, more and more people are starting to use proxy servers and proxy IPs to protect their privacy and security, or to bypass certain restrictions and blockades. When choosing proxy servers and proxy IPs, many people will notice that foreign server proxy IPs can only be used in an overseas network environment. Why is this?
Why do foreign server proxy IPs need to be used in an overseas network environment?
Before understanding why foreign server proxy IPs need to be used in overseas network environments, let us first understand the basic principles of proxy IPs.
Proxy IP is a network proxy technology that hides and forges the client's real IP address by inserting a proxy server between the client and the target website. When the client sends a request to the target website, the proxy server will send the request to the target website on behalf of the client and forward the data returned by the target website to the client. In this way, the target website cannot obtain the client's real IP address, thereby protecting the client's privacy and security.
The reason why foreign server proxy IPs can only be used in overseas network environments is mainly because the domestic network environment has strict restrictions on proxy servers and proxy IPs. Specifically, the domestic network environment has the following restrictions:
1. IP address segment restriction: Domestic network operators will restrict access to some foreign IP address segments, thereby preventing clients from accessing foreign websites through proxy servers and proxy IPs.
2. DNS pollution: There is DNS pollution in the domestic network environment. That is, during the DNS resolution process, the network operator will tamper with the returned IP address, making it impossible for the client to correctly access the target website.
3. Firewall restrictions: The domestic network environment has relatively strict network firewalls that will monitor and block proxy servers and proxy IPs, thereby restricting clients from using proxy servers and proxy IPs to access foreign websites.
Therefore, in order to use the foreign server proxy IP normally, the client needs to access the proxy server through the overseas network environment to bypass the restrictions of the domestic network environment. Specifically, the client can access the proxy server in the following ways:
1. Renting overseas servers: The client can access the proxy server by renting overseas servers. To rent overseas servers, you can choose some large international cloud server providers, build your own server overseas, and then install the proxy server on the server. The client can then access the proxy server through the server.
2. Use overseas proxy software: Clients can use some overseas proxy software to connect to overseas proxy servers to access foreign websites.
What kind of business can foreign server proxy IP do?
Foreign server proxy IP can be used for a variety of businesses, including the following:
1. Network security and privacy protection: Using a proxy IP can hide the client's real IP address, thereby protecting the client's privacy and security and preventing personal information leakage and network attacks.
2. Bypass blockades and restrictions: Some regions will block and restrict certain websites. Using proxy IP can bypass these blockades and restrictions and access restricted websites.
3. Data collection and crawling: Using proxy IP can realize data collection and crawling of target websites, avoiding being blocked or restricted by the target website.
4. Overseas games and videos: Some overseas game and video websites may restrict domestic IP addresses. Using a proxy IP can enable access to these overseas game and video websites.
5. SEO optimization: Using proxy IP can optimize search engines, such as access to search engines such as Google and Bing, thereby improving the website's SEO ranking.
How to choose a foreign server proxy IP?
Choosing a foreign server proxy IP that suits you needs to consider many aspects, including the following:
1. Geographical location: The client needs to select a proxy server that is closer to itself to reduce access delay and increase access speed.
2. Bandwidth and speed: The client needs to select a proxy server with faster bandwidth and speed to ensure smooth and stable network.
3. Security and privacy: The client needs to choose a proxy server with better security and privacy protection to avoid personal information leakage and network attacks.
4. Price and cost-effectiveness: The client needs to choose a proxy server with reasonable price and high cost-effectiveness to reduce the cost of use.
In summary, foreign server proxy IPs can only be used in overseas network environments, mainly because the domestic network environment has strict restrictions on proxy servers and proxy IPs. Foreign server proxy IPs can be used for a variety of businesses, including network security and privacy protection, bypassing blockades and restrictions, data collection and crawling, overseas games and videos, SEO optimization, etc. When choosing a foreign server proxy IP, you need to consider multiple aspects, including geographical location, bandwidth and speed, security and privacy, price and cost-effectiveness, etc.
