With the popularization and rapid development of the Internet, network concepts such as proxy IP addresses and bandwidth IP addresses have gradually become well known to people. However, many people often confuse the two in practical applications and are not clear about the differences and connections between them. This article will elaborate on the differences between proxy IP addresses and bandwidth IP addresses, as well as the advantages of proxy IP addresses.

1. The difference between proxy IP addresses and bandwidth IP addresses

1. Different definitions

Proxy IP addresses refer to the IP addresses used by proxy servers during network requests. When a user sends a network request, the request data is first sent to the proxy server, and then the proxy server forwards the request data to the target server. In this process, the proxy server uses a proxy IP address. The bandwidth IP address refers to the IP address assigned to the user by the network operator, also known as the public IP address. This address is the unique identifier of the user in the network and is also the address where the user is accessed on the Internet.

2. Different functions

The main function of the proxy IP address is to hide the user's real IP address and protect the user's privacy and security. When a user sends a network request through a proxy server, the target server can only see the IP address of the proxy server, but cannot know the user's real IP address. In addition, the proxy server can also cache and accelerate network requests to increase network access speed. The bandwidth IP address is the unique identifier of the user being accessed on the Internet, which allows other users to access the user's computer or server through this address.

3. Different ranges

The range of proxy IP addresses is usually much smaller than that of bandwidth IP addresses. A proxy server usually contains only a few to dozens of proxy IP addresses, while the bandwidth IP address is a unique identifier assigned by the network operator to each user, which is huge in number.

2. Advantages of proxy IP addresses

1. Protect privacy and security

As mentioned above, the proxy IP address can hide the user's real IP address and protect the user's privacy and security. When sending sensitive information or visiting certain specific websites, using a proxy IP address can avoid the user's real identity from being leaked and reduce the risk of being attacked by the network.

2. Improve network access speed

Proxy servers usually have a high-speed cache function, which can cache frequently visited web page content, reduce network delays, and increase network access speed. In addition, proxy servers can also accelerate network requests to make web pages load faster.

3. Break through geographical restrictions

In some countries and regions, network content may be subject to geographical restrictions. Using proxy IP addresses can break through these restrictions and allow users to access website content in different regions. For example, websites that cannot be accessed directly in certain countries or regions can be accessed normally through proxy servers.

4. Defense against DDoS attacks

Proxy servers can serve as a line of defense against DDoS attacks. When attackers send a large number of invalid requests to the target website, proxy servers can help share part of the request volume, reduce the burden on the target website, and improve its anti-attack capabilities.

In short, although proxy IP addresses and bandwidth IP addresses are both types of IP addresses, their functions and application scenarios are very different. Proxy IP addresses have the advantages of protecting privacy and security, increasing network access speed, breaking through geographical restrictions, and defending against DDoS attacks, while bandwidth IP addresses are the unique identifier of users on the Internet. When choosing to use proxy IP addresses, you need to select and configure them according to actual needs and application scenarios.
