As we all know, there are many types of proxy IP, such as forward proxy, reverse proxy, HTTP proxy, SOCKS proxy, data center proxy, residential proxy, and so on. So according to what criteria are these various types of agents divided? Next, take you to understand the division of proxy IP types and common types of related knowledge.
First, divided by price
Price is almost the first factor that users pay attention to, according to the price of the agent IP can be divided into free agent and paid agent two kinds:
1. Free agency
A free proxy is a proxy IP that users can use without paying a fee. Users can obtain free proxy IP resources by searching on the Internet or using websites, forums and other channels provided by free proxy IP. While the use of free agents may be appropriate for some simple needs, they often have some limitations and disadvantages.
Slow proxy: Free proxy IP is often provided by unstable servers that may be limited in bandwidth and processing power. As a result, the response time of free agents is slow, which can cause problems with prolonged page load times or connection timeouts.
Lower degree of anonymity: Because free proxy IP is widely shared, it is less anonymous. This means that when using a free proxy for access, the target website may be able to detect the user's real IP address and cannot truly protect the user's privacy.
Instability and unreliability: The availability and stability of free proxy IP is generally poor. Because the supplier does not provide stable support and maintenance for free proxy IP addresses, these proxy IP addresses may often fail to connect, frequent disconnection, and instability, affecting the normal user experience.
Security risk: The security of the free proxy IP cannot be guaranteed. Some bad free proxy providers may quietly monitor and record users' network activities, and even use users' personal information and data for other nefarious purposes.
2. Paid agency
Paid agent is a more mainstream agent form at present, and users need to pay fees to agent service providers to obtain services. Compared with free agents, paid agents have higher advantages in terms of speed, anonymity and business success rate.
Offer faster speeds: Paid proxy services are typically deployed on high-speed, stable servers with greater bandwidth and a more optimized network architecture. This allows users to enjoy faster proxy connection speeds, reduced page load times, and improved access efficiency.
Provide greater anonymity: Paid proxy services typically provide more anonymity protection. They can hide a user's real IP address and forward requests through multiple layers of proxies, making it impossible for the target website to track the user's true identity. This is important for users who need to protect their privacy and prevent tracking or surveillance.
Provide higher business success rate: Due to the better performance and stability of paid agent services, users are more likely to successfully complete various business operations when using paid agents. Whether it's crawler data collection, access to restricted websites, online advertising, or other tasks that require stable and reliable agent support, paid agents offer higher success rates and reliability.
Provide better customer support: Paid agency services usually provide a professional customer support team that can answer users' questions, provide technical support and solutions in a timely manner. Users can get a better service experience and get timely help when they encounter problems.
Second, divided by direction
The proxy direction defines which end of the connection benefits from the proxy server - the user sending the request or the server receiving the request.
1. Forward proxy
The forward proxy is the mainstream proxy that users are exposed to. The proxy server serves the user client and helps users secure access requests and access their own IP addresses.
2. Reverse proxy
The reverse proxy serves the site server, such as the online customer service, telephone consultation and so on that we usually come into contact with, which are all played by the reverse proxy server.
Third, by source
There are two common types of proxy IP paid by source, residential and data center:
1. Residential agent
Residential agents are IP addresses belonging to real mobile and desktop devices, and these agents will be considered by the website as real users, with a high degree of concealment. Residential agents are an excellent choice for accessing protected websites and handling location-sensitive information.
2. Data Center agent
Data center agents get IP addresses from servers in the data center, which are not part of real-life devices and are therefore more likely to be blocked in some cases. A big advantage of using a data center broker is faster speeds and lower prices.
Iv. Division by agreement
Proxy protocols define how users connect to websites or services on the Internet. There are three main proxy types: HTTP proxy, HTTPS proxy, and SOCKS proxy.
1. HTTP proxy
HTTP proxy is the current mainstream proxy type that uses the HTTP protocol compatible with websites to send all traffic in plain text.
2. HTTPS proxy
HTTPS proxy is a secure proxy that uses the SSL protocol to encrypt data, making it harder for data to be stolen in transit.
3. SOCKS proxy
The SOCKS proxy works at a lower level than the HTTP (S) proxy, but the advantage of the SOCKS proxy is that it is versatile and supports multiple protocols.
These are the common proxy IP types and their introduction. Different proxy IP address types apply to different scenarios. You can select a proxy IP address type based on your requirements to achieve secure and stable proxy access.
