The ISP database generally contains the ISP name. However, when we are not able to obtain the ISP we include the name of the organization the IP address block was assigned to. For example, the ISP database often contains the names of universities instead of the universities’ ISPs.
When only the ISP or organization name is available, both the GeoIP ISP and Organization databases return the same value. In such cases, the shared value usually represents the ISP. When both the ISP and organization names are available, the GeoIP ISP and Organization databases return the ISP and organization, respectively.
