Proxy IP refers to the IP address used when accessing the Internet through a proxy server. Proxy IP can hide the real IP address and protect the user's personal information security.
The availability rate of HTTP proxy IP refers to the probability that the proxy IP can successfully access the target website. In actual situations, due to various reasons, the availability rate of HTTP proxy IP often cannot reach 100%.
- Network fluctuations: The network environment is constantly changing, and sometimes international lines may become unstable, causing some proxy IPs to be unable to access the target website. In this case, it is necessary to improve the availability of proxy IPs by optimizing lines, upgrading equipment, etc.
- Target website restrictions: Some websites will restrict the IP addresses of visitors to protect website resources and prevent malicious behavior. When the proxy IP used is blacklisted by the target website, the proxy IP will be unable to access the website. 3. Domestic firewall policy: In order to maintain network security and national interests, my country has implemented access restrictions on some foreign websites. This may affect the availability of some proxy IPs.
- User behavior: Some users may use proxy IPs to conduct illegal activities, such as sending spam, malicious attacks, etc. Such behavior will cause the proxy IP to be banned, thereby reducing the availability of the entire proxy IP pool.
To sum up, the availability of HTTP proxy IP is not 100% due to many reasons. When choosing a proxy IP, if the availability of the proxy IP is 99%, it can be considered as high quality and high availability.
