Choosing a proxy IP requires careful consideration of the network node as it directly affects the quality of the proxy IP. Generally, the more nodes available, the higher the quality of the proxy IP, as it improves reliability, stability, and provides users with more choices. Conversely, a limited number of nodes may decrease reliability, stability, and limit users' options. Therefore, it is crucial to choose a proxy IP with many nodes.

Having more proxy IP nodes also reduces IP duplication rates since a wide distribution range lowers the repetition rate. As IPv4 networks are scarce globally, paying attention to the number of nodes when selecting a proxy IP helps to reduce the duplication rate and improve the IP quality.

In addition, the more nodes a supplier invests in, the stronger their ability, making their services more reliable and potentially stable. It is essential to consider the number of nodes, price, and supplier's strength when selecting a proxy IP.

A proxy IP with more nodes provides users with more choices, especially if the nodes cover multiple regions. This way, users can easily find a suitable proxy IP that meets their needs. In contrast, limited nodes can lead to inadequate choices and not satisfy user requirements.

Using multiple proxy IPs increases the success rate of business processing as it makes it challenging for websites to identify the user's actual location. However, using only one proxy IP may cause processing failure as the website may recognize the proxy IP's location. Therefore, a larger number of proxy IP nodes increases the success rate of business processing.
