An ISP proxy is a server whose IP address is assigned to users by their Internet Service Provider, or ISP for short. These agents do not include end users' mobile phones or desktop computers. Instead, ISP proxies are hosted on servers. ISP proxies are static in nature in terms of proxy port and session type. For this reason, they are also called static residential proxies, which are sometimes boiled down to simple static proxies.

Single ISP means that one type of the agent is ASN and the other type is company. The ASN in some residential IPs belongs to the operator, but the company does not. This is a single ISP. The real residential IP, whether it is the ASN or the operating company, should be the local operator, and the name of the operator is generally displayed.

Dual ISP means that one type of the agent is ASN, and the other type is company. In some residential IPs, the ASN belongs to the operator, but the company does not. This is a single ISP; and for real residential IPs, whether it is ASN or operator The companies should all be local operators, and generally the name of the operator is displayed.

Single ISP and dual ISP mainly differ in the following three aspects:

Reliability of network connection: Dual ISP connects two different ISPs at the same time. When one ISP's network fails or becomes unstable, the other ISP can provide services as a backup network to ensure that the user's network continues to operate stably. When a single ISP faces network failure or instability, it may not be able to provide continuous and stable services.

Bandwidth and speed: Dual ISP can achieve greater bandwidth and faster speeds by connecting to two different ISPs at the same time, especially when processing large amounts of data or performing complex network operations. In comparison, the bandwidth and speed of a single ISP may not reach the same level.

Cost-Effectiveness: Dual ISP requires paying for two different services and may require additional equipment and configuration to manage dual connections. Therefore, users need to weigh the balance between cost and performance. The cost of a single ISP is relatively low, but it may not provide the performance of a dual ISP.

In general, single ISP and dual ISP have their own advantages, and users need to choose the appropriate service based on their needs and budget. For scenarios that require high network bandwidth and stability, dual ISP may be a better choice.
