ISP data describes the access provider

An ISP field can help explain whether a request came through a consumer broadband provider, a mobile network, a business provider, or a hosting environment.

Provider context helps support

When customers report access issues, knowing the provider can help identify regional routing, carrier behavior, or expected corporate networks.
