A proxy IP is a technology that relays data traffic through a server, hiding the user's real IP address and replacing it with the IP address of the proxy server. When a user sends a network request to another website, the request passes through the proxy server, which then communicates with the target website, thereby concealing the user's real IP address information.

Proxy IPs can be divided into two types: rotating proxy IPs and static proxy IPs:

Rotating proxy IP:Refers to switching between multiple different IP addresses within a set period, as configured by the provider.

Static proxy IP:A set of IP addresses owned by the provider at a specific location. All proxy requests are forwarded to this server, keeping a fixed IP address.

Proxy IPs have many uses, such as privacy protection, anti-scraping, and cross-border e-commerce, but their legality must also be considered, and relevant regulations must be followed when using them.

How to obtain proxy IPs

A proxy IP typically consists of an IP address, a port, an account, and a password. The IP address is the address of the proxied server, the port is the numerical identifier used for transmitting data between network applications, and the account and password are the authentication credentials required to access the proxy server.
By using a proxy IP, users can hide their real IP address to protect their privacy and security. Proxy IPs can also help users overcome geographic restrictions and access blocked websites and content.

There is also another form: access via IP whitelisting, which requires no username or password.

What types of proxy IPs are there?

There are many types of proxy IPs, and each suits different scenarios. Choosing the right type can improve access speed and stability.

Proxy IPs classified by request protocol:

1. HTTP proxy:HTTP proxy is one of the most common proxy types. It supports only the HTTP protocol and is suitable for browsing web pages, sending emails, and similar tasks.

2. HTTPS proxy:An HTTPS proxy is a proxy type that supports the HTTPS protocol. Compared with HTTP proxies, it is more secure and suits scenarios that require encrypted data transmission.

3. SOCKS proxy:SOCKS proxy is a fairly general-purpose proxy type. It supports TCP/UDP and various application-layer protocols, and is not limited to HTTP and HTTPS. Compared with HTTP and HTTPS proxies, SOCKS proxies are faster but more complicated to use.

4. FTP proxy:FTP proxy is a proxy type designed specifically for the File Transfer Protocol, suitable for uploading and downloading files.

5. Tunnel proxy:A tunnel proxy operates at the network layer. It establishes a virtual channel between proxy servers running at both ends, encapsulating the proxied data packets before transmitting them. Tunnel proxies are commonly used to bypass firewalls and other blocking measures.

Proxy IPs classified by anonymity level:

1. Transparent proxy:A transparent proxy does not modify any content of the client's request, and the client can use it without any special configuration. However, a transparent proxy cannot hide the client's real IP address and is easily detected and blocked.

2. Anonymous proxy:An anonymous proxy hides the client's real IP address but does not modify the client's requests. Clients can use certain special methods to detect that an anonymous proxy is being used.

3. High-anonymity proxy:Elite proxies also hide the client's real IP address and further disguise the client's request headers and other information, making the client harder to identify and trace. Compared with transparent and anonymous proxies, elite proxies offer higher security and better stability, but they are also relatively more expensive.

Proxy IPs classified by commercial allocation:

Rotating proxy IP

Rotating proxy IPs are proxy servers that periodically change their IP addresses during use, allowing clients to switch IPs automatically and reduce the risk of being blocked or detected.
Compared with static proxy IPs, this type is harder for target websites to identify and block, since the proxy server constantly changes its IP address, ensuring the effectiveness and stability of the proxy IPs. Rotating proxy IPs are typically suited for scenarios that require large numbers of IP addresses, such as web crawling, data collection, search engine optimization, and anonymous browsing.

Static Proxy IP

Static proxy IPs are proxy servers that provide a fixed IP address that never changes. A client using a static proxy IP connects to the proxy server with the same IP address every time
The address stays unchanged for a long time, making it suitable for account operations that require a fixed login location, ad placement, and businesses that need IP whitelisting. However, when a single IP receives too many requests, it is easily throttled or blocked by target websites, so it is not suitable for large-scale collection.

Residential Proxy IP

Residential proxy IPs are IP addresses from ordinary household networks (such as China Telecom, China Unicom, China Mobile, etc.) that serve as proxy servers for other clients to access.
This type of proxy is often used in scenarios that require simulating real user behavior, as residential proxy IPs are more likely to earn the trust of target websites and avoid being identified and blocked. Compared with datacenter proxy IPs, residential proxy IPs are somewhat less stable and reliable, and because they have more users, bandwidth and speed may also be affected.

Data center proxy IP

Datacenter proxy IPs are IP addresses provided by data center or managed hosting providers (such as Amazon, Google, Alibaba Cloud, Tencent Cloud, Baidu AI Cloud, etc.) that serve as proxy servers for other clients to access.
This type of proxy is often used in scenarios that require large-scale data scraping, as datacenter proxy IPs offer high stability, fast speeds, and ample bandwidth. Compared with residential proxy IPs, datacenter proxy IPs are more easily identified and blocked by target websites, but because they have fewer users, they are relatively more stable and reliable.

Mobile proxy IP

Mobile proxy IPs are IP addresses provided by mobile carriers, usually dynamic IPs assigned through mobile phones or other mobile devices (such as 4G routers).
Using mobile proxy IPs lets you simulate the authentic identity of mobile users, since mobile devices differ from PCs in operating systems, browsers, and network environments, making them especially useful for data scraping or testing scenarios that require mobile simulation. However, because mobile proxy IPs have poor real-time performance and are easily affected by carrier interference and restrictions, they are relatively less stable than residential and datacenter proxy IPs. In addition, since mobile proxy IPs are used heavily, they are also easily detected and blocked by target websites.

Use cases for proxy IPs

Rotating proxy IP use cases

Applicable scenarios:Web crawling proxies, mass email sending, SEO optimization, boosting ad traffic

Cons:Cannot be used long-term, expensive, and easily blocked

  • What is a web crawler proxy IP?A crawler proxy is a proxy server used when scraping website data. It helps hide your real IP address and avoid being banned or having your access frequency limited. Crawler proxies can also bypass some anti-scraping mechanisms by rotating different IP addresses, effectively improving data scraping efficiency and success rates.

    Summary

    A proxy IP is an intermediary entity that relays network information between a client and a server. The device or software using a proxy IP does not communicate directly with the target server. Instead, it sends requests to a proxy server, which forwards the requests, retrieves the response data, and then transmits the response back to the requester, thereby protecting privacy, penetrating firewalls, and countering anti-scraping measures.

    Proxy IPs can be categorized into HTTP proxies, HTTPS proxies, SOCKS proxies, anonymous proxies, transparent proxies, elite proxies, and more. They have a wide range of applications, such as data collection, cybersecurity testing, geo-targeted advertising, and online marketing. At the same time, the quality of proxy IPs varies greatly. High-quality proxy IPs can improve crawling success rates and enhance privacy and security, while low-quality proxy IPs may waste time and money and cause more problems.
