Why one IP address is associated with multiple organizations?

I broke down the IP address ranges into individual IPs. Why does one IP address range have multiple attributes?

Generally, you should not expand or break down IP address ranges to their individual IP address from our database to run queries. Our databases are designed for optimized data queries, and we flatten and aggregate IP address ranges for fast IP queries.

The flattening process of IP addresses only shows the final assignment of the IP address or the last organization in the hierarchy. When you expand each IP range, you might come across one IP being associated with multiple organizations. IP address range assignments are often indirect.

For example, a big IP address range can be assigned to an ISP, which can assign a subset of that IP address range to one of their enterprise customers, then that organization can assign a smaller range of IP addresses to one of their subsidiary companies.
