Proxy IP is widely used in web crawler, network marketing, multi-account registration and other scenarios. However, in the process of using the IP proxy, we may encounter some cases of IP failure, or choose a low-quality IP proxy, resulting in the proxy IP is not available. Therefore, we need an efficient way to check whether the IP proxy is available to ensure the smooth completion of our mission. The following describes several common IP proxy validity verification methods:
1. Information comparison:
Message comparison is a simple and direct verification method used to check the validity of proxy IP addresses. This method does not involve any complicated technical operation. It only needs to determine whether the proxy IP is valid by comparing the real IP used by the current network with the IP obtained after visiting the target website using the proxy IP.
First, we can check the IP address of the current network connection through the browser or network Settings, which is our real public IP address. Next, we access the target website using a proxy IP, which can be obtained using a dedicated proxy IP provider or pool of proxy IP. After visiting the destination website, we can again view the current IP address, that is, the IP address obtained after visiting through the proxy IP.
①What is the difference between IP and proxy ip?
If the real IP is not the same as the IP address after the proxy IP is accessed, then we can conclude that the proxy IP is valid and that it successfully hides our real IP address. Such a verification method is suitable for verifying a small number of IP addresses, especially if we only need to verify a few proxy IP addresses, which is very convenient and fast.
2. Server detection:
Server detection is one of the more common and relatively accurate verification methods used to check the validity of the proxy IP. Compared with information comparison, server detection can quickly verify whether a large number of IP addresses are available, and is suitable for verifying proxy IP addresses in batches.
In server detection, we need to replace the proxy IP address with the local IP address and then visit the target server or website. If the server can return the result correctly, the proxy IP is valid, and it was able to successfully establish a connection with the server and obtain the data. This approach can better simulate real-world usage scenarios, because the ultimate goal is to access a specific server or website through a proxy IP to ensure that the proxy service works.
②How does the HTTP proxy and HTTPS proxy work and flow?
However, there are some issues that we need to be aware of when using server detection methods. Some sites may restrict frequent proxy IP requests to prevent abuse or trigger anti-crawler mechanisms. Therefore, when conducting a large number of IP authentication, we need to control the frequency of requests to avoid requesting the same server too frequently, so as to avoid being blocked or restricted by the server. You can set an appropriate request interval to ensure the rationality and stability of the request.
In addition, because the server's response time and load may affect the validation results, we should also pay attention to request timeouts. If a proxy IP address frequently times out during multiple authentication, it may indicate that the proxy IP address is not stable enough, and you need to replace it with another available proxy IP address.
3. Use tools:
Using tools is an efficient and convenient way to do this, especially when you need to validate a large number of IP agents. With dedicated IP proxy validation tools, we can automatically verify the validity of multiple ips and get corresponding results reports, so that we can quickly understand which proxy IP is available and which is not.
IP proxy authentication tools usually provide a variety of authentication methods and setting options, such as server connection tests, target website access tests, and so on. Users only need to enter the list of proxy IP addresses to be verified, and the tool will automatically verify and return the verification result. This makes the verification process more automated and efficient, saving a lot of time and effort to manually compare IP.
In summary, verifying the validity of an IP proxy is a key step in ensuring the availability of proxy IP. According to the actual demand and the number of IP addresses, selecting the appropriate authentication method can help us use IP agents more efficiently, improve work efficiency, and successfully complete the task.
