IP proxy IP nodes come from several different sources, each of which has its own specific way of collecting or generating IP addresses. Let's explore these sources in detail:

1. Data center proxies:

These IP addresses come from data centers.

Data centers have a large number of servers and IP addresses, which are purchased or rented by proxy service providers.

Because these IP addresses are concentrated in certain specific data centers, they are easily identified as proxy addresses.

2. Residential proxies:

From real users' home networks.

Usually obtained through cooperation with Internet service providers (ISPs), or through software clients, ordinary users' devices are converted into proxy nodes.

Users may share their network connections in exchange for certain benefits (such as free use of software, increased network bandwidth, etc.).

These IP addresses look like the network traffic of ordinary home users, making them difficult to be identified and blocked by websites.

3. Mobile proxies:

IP addresses from mobile devices, such as smartphones.

Obtained through cooperation with mobile network operators, or using specific software to use mobile devices as proxy nodes.

These IP addresses represent real mobile network users and can be used to simulate the network behavior of mobile users.

P2P (peer-to-peer) proxy network:

Get IP addresses by building a large network of user devices.

Users agree to make their devices part of the network by installing specific P2P software.

When other users send requests through the network, these requests may be forwarded through these P2P nodes.

4. Hybrid proxy:

Some proxy services may combine the above methods to provide hybrid proxy services with both data center IPs and residential or mobile IPs.

In summary, the sources of proxy IP nodes are diverse, and each type of IP address has its specific acquisition method and purpose. Choosing which type of proxy IP depends on user needs, such as anonymity, stability, speed, and cost.
