An Internet Service Provider (ISP) proxy is a type of proxy that is provided by an Internet Service Provider (ISP) to its customers. These proxies are typically used to access the Internet and are assigned to a specific user or device by the ISP. They are usually transparent proxies, meaning that they do not hide the IP address of the user or device that is using them.

On the other hand, residential proxies are IP addresses that are associated with a specific physical location, such as a home or office. These proxies are not provided by an ISP, but rather are obtained through a proxy service that rents them from real Internet users who have agreed to share their IP addresses.

There are several key differences between ISP proxies and residential proxies:

1. Ownership: ISP proxies are owned and controlled by the ISP, while residential proxies are owned and controlled by the individual or company that rents them.

2. IP addresses: ISP proxies have IP addresses that are associated with the ISP, while residential proxies have IP addresses that are associated with a specific physical location.

3. Transparency: ISP proxies are usually transparent, meaning that they do not hide the IP address of the user or device that is using them. Residential proxies, on the other hand, are designed to hide the user's IP address and provide anonymity.

4. Use cases: ISP proxies are typically used for accessing the Internet and are assigned to a specific user or device by the ISP. Residential proxies, on the other hand, are often used for tasks that require a high level of anonymity, such as web scraping, sneaker purchasing, and managing multiple social media accounts.

In conclusion, ISP proxies and residential proxies are two different types of proxies that serve different purposes. ISP proxies are provided by an ISP and are typically used for accessing the Internet, while residential proxies are rented from real Internet users and are used for tasks that require a high level of anonymity.
